- freeCommmunicatorComponents needs an additional bounds check.
When MPI is initialized outside of OpenFOAM, there are no
UPstream communicator equivalents
- the output write scaling should be applied *after* undoing the
effects of the specified rotation centre. Fixes#2566
ENH: update option names for transformPoints and surfaceTransformPoints
- prefer '-auto-centre' and '-centre', but also accept the previous
options '-auto-origin' and '-origin' as aliases.
Changing to '-centre' avoids possible confusion with
coordinate system origin().
- add overflow() method to the SHA1 streambuf. Previously could rely
on xsputn for adding to sha1 content, but streams now check pptr()
first to test for the buffering range and thus overflow() is needed.
- when used for example with wallShearStress, the stress field is
initially created as incompressible but later updated with the
correct compressible/incompressible dimensions.
If this field is sampled as a surface and stored on the registry
the dimensions should be reset() and not '=' assigned, since that
causes a dimension check which will obviously fail.
- setup writer outside the data loop to ensure that the number of
output fields is correct (VTK format).
- ignore 'interpolate' on sampled surfaces to ensure proper
face sampling, never allow point sampling
BUG: incorrect debug-switch for sampledIsoSurface
The polyMesh construct-from-components will now ignore
the readOpt for the supplied primitives as before.
This again re-allows READ_IF_PRESENT for fv* in
combination with supplied primitives.
This makes the initialisation order of dynamicMesh consistent
with plain ones using the virtual mechanism. It does not
solve the cyclicACMI construction order yet.
Changed IO flag so that new mesh is created
- was using old 'faces', 'owner' etc but then used the new patch starts
Corrected logic for contMap in polyTopoChange
walls
A new user input parameter UrMax is added to the PatchInteractionModel.
In some occasions the partile remains on a patch face due to extremely
low relative U. If this Ur is lower than UrMax the particle is removed
- replaces previous code that used an autoPtr to hold a singleton.
In some circumstances this deletion would conflict with clearing
the objectRegistry - leading to error messages on exit.
Now store directly on the registry (similar to a MeshObject)
- previously hard-coded, now adjustable within PDRsetFieldsDict
// Change some predefined patch names
patchNames
{
ground ground;
outer outer;
}
ENH: additions to PDRutils, improve comments
- expose enumerated expansion names and gridControl (PDRblock).
Not commonly needed, but useful to have access when defining
other grid generators
TUT: update PDRsetFieldsDict and tutorials to use "ground"
- remove tutorial references to unused types and legacy obstacles
- use "ground" for the boundary conditions instead of "seaGround".
Consistent with PDRblockMesh
The new functionality optionally allows the patch-averaged
value to be scaled and/or offset by a pair of specified values.
Example of the boundary condition specification:
```
<patchName>
{
// Mandatory entries (unmodifiable)
type outletMappedFilterInlet;
outletPatch <outletPatchName>;
// Optional entries (unmodifiable)
fraction 0.1;
offset 10; // (1 0 0);
phi phi;
// Optional (inherited) entries
...
}
```
1) PhaseIncompressibleTurbulenceModel class was changed to use
uniform alpha and non-uniform rho templates. This fits the need
of incompressible two phase turbulence models.
2) A new type DPMIncompressibleTurbulenceModel was created for
non-uniform alpha and uniform rho. It is used in single phase flows
in DPM solvers where alpha represents the volumen occupancy.
3) A new type incompressibleRhoTurbulenceModel was created where
non-uniform rho is allowed.
4) A new base templated turbulent class for two-phase VOF named
VoFphaseTurbulentTransportModel was implemented which is created
templating on PhaseIncompressibleTurbulenceModel and
incompressibleRhoTurbulenceModel
5) In order to make the chnage to rho based VOF turbulence a help
class was added incompressibleInterPhaseTransportModel templated
on the mixing.
In reconstruct mode redistributePar will have
- master read undecomposed mesh
- slaves construct dummy mesh (0 faces/points etc.)
but correct patches and zones
so all processors have two valid meshes. This was
all handled inside fvMeshTools::newMesh and this
was behaving differently.
Function1 wrapper that limits the input range of another Function1
Example usage for limiting a polynomial:
limitedPolyTest limitRange;
limitedPolyTestCoeffs
{
min 0.4;
max 1.4;
value polynomial
(
(5 1)
(-2 2)
(-2 3)
(1 4)
);
}
Here the return value will be:
- poly(0.4) for x <= 0.4;
- poly(1.4) for x >= 1.4; and
- poly(x) for 0.4 < x < 1.4.
- previously always called dlclose on opened libraries when destroying
the dlLibraryTable. However, by force closing the libraries the
situation can arise that the library is missing its own code that it
needs on unload (#1524). This is also sometimes evident when closing
VTK libraries for runTimePostProcessing (#354, #1585).
- The new default is to not forcibly dlclose any libraries, unless
the dlcloseOnTerminate OptimisationSwitch specifies otherwise.
- The dlLibraryTable::close() method can be used to explicitly close
all libraries and clear the list.
- The dlLibraryTable::clear() method now only clears the entries,
without a dlclose.
Failures shown in interFoam cases were found to be a result of stale ldu
addressing in fvMesh. Potentially delete lduPtr_ alone, but likely safer to
clear all addressing:
// deleteDemandDrivenData(lduPtr_);
clearAddressing(true);
The FO BilgerMixtureFraction needs access to specieComposition which is
stored in ReactingMixture. A virtual mechanism was added to
basicSpecieMixture to access specieComposition form rho and psi
reationThermos.
ptr was changed to autoPtr to avoid memory leaks (Kutalmis Bercin)
Multiplies a given list of (at least two or more) fields and outputs the
result into a new field.
fieldResult = field1 * field2 * ... * fieldN
Minimal example by using \c system/controlDict.functions:
multiply1
{
// Mandatory entries (unmodifiable)
type multiply;
libs (fieldFunctionObjects);
// Mandatory (inherited) entry (runtime modifiable)
fields (<field1> <field2> ... <fieldN>);
...
}
- now also tracks the previous output time, which aids on restarts
since it allows the FEA side the possibility of determining
the effective deltaT between the output of forces
COMP: fix SP/DP inconsistency in fvGeometryScheme
STYLE: rename polyMesh::updateGeom to polyMesh::updateGeomPoints
- avoids compiler complaints and potential masking of
primitiveMesh::updateGeom / fvMesh::updateGeom
- mark argument as movable, since that is what is happening inside.
GIT: remove merge cruft
TUT: better clean on MPPICInterFoam
The SPL can now be weighted according to the new 'SPLweighting' entry
that can be set to:
- none: no weighting
- dBA : dB(A)
- dBB : dB(B)
- dBC : dB(C)
- dBD : dB(D)
This commit also includes code refactoring of the noiseModel class to
remove the dependency on noiseFFT/declutter.
Affected only the first optimisation cycle, if line search was enabled
If eta was not set explicitly, it was computed after evaluating the
directional derivative of the merit function, which was computed
wrongly, leading to an erroneous value of the extrapolated merit
function value.
fvOptionsAdjoint was needlessly duplicating a lot of the functionality
of fvOptions in order to add an interface for computing sensitivity
contributions emerging from fvOptions. To reduce this code duplication:
- fvOptionsAdjoint was removed
- the corresponding sensitivity contributions have moved to fvOptions through
virtual functions (returning a zero contribution in the base so
backwards compatibility is retained)
- all sensitivity classes that were using fvOptionsAdjoint have been
modified appropriately
- all adjoint solvers are now grabbing a reference to an fvOptionList
from the database instead of constructing an fvOptionsAdjointList
Hence, all fvOptions contributions to the adjoint equations
or the sensitivity derivatives can be given through system/fvOptions,
removing the need for separate sub-dictionaries within optimisationDict.
- Expanded the write function in the base class so that it can manage
input coming from the derived ones. This reduces a lot of code
duplication in the latter but keeps the functionality.
- Added a default width for all entries in the objective files.
- If a normalisation factor or a target is set, they are written on the
header of the objective file.
- Cosmetic/code consistency changes in various files.
- Added preLoop, loop and postLoop functions
- Added preIter, mainIter and postIter functions for each SIMPLE
iteration
- Added addMomentumSource and addPressureSource virtual functions, to
allow for additions by derived classes
fvOptions are no longer a member of incompressiblePrimalSolver but are
looked up from the registry in each iteration of each primal solver.
This means that the main system/fvOptions dictionary is read by ALL
instances of the primal solvers and the latter no longer have their
own fvOptions dict in optimisationDict. This is safe since each fvOption
is applied to a specific field and in case of many primal solvers, the
primal fields are named differently for each of them.
In addition, simple is now split in preLoop, loop and postLoop phase.
Furthermore, each SIMPLE iteration is broken down to
a preIter, mainIter and postIter phase, to allow for different behaviour
by derived classes.
Part of the (E)SI shape sensitivities depends of grad(Ua) & nf computed
on the boundary. Up to now, the code was only computing the normal part
of grad(Ua), to avoid the potentially spurious tangential component
which is computed on the cell center and extrapolated to the boundary
faces. However, for some objectives that are strongly related to the
stresses (e.g. moment, stresses), including also the tangential part of
grad(Ua) is necessary for E-SI to replicate the outcome of FI.
Extensive testing on a number of objectives/cases showed
- No regression when including the tangential part
- Improved behaviour in some rare cases (moment, stresses)
Hence, the tangential part is now included by default. The previous code
behaviour can be replicated by setting the useSnGradInTranposeStresses
flag to true.
- controlPointsDefinition is now controled by a class with
runTimeSelection.
- Added a new controlPointsDefinition option that translates, rotates
and scales a given box. The required entries have the same meaning as
in the Paraview 'Transform' filter, facilitating the transition between the
visual placement of control boxes (e.g. in Paraview) and their setup
in the code.
- Improved performance during the parameterization, sensitivity
computation and grid displacement phases by re-using already computed
basis functions.
- adds topology-based segmentation of the surfaces generated with
distance surfaces. This can occur when the surface terminates
close to a thin wall gap in the mesh; resulting in a cuts that
extend into the next region.
The cutting algorithm does not normally distinguish between these
types of "ragged" cuts, and legitimate ones (eg, cutting multiple
pipes). The additional segmentation controls provide for two common
scenarios:
largestRegion (pre-filter):
- The cut cells are checked for topological connectivity and the
region with the most number of cut cells is retained.
This handles the "ragged" edge problem.
nearestPoints (pre-filter):
- The cut cells split into regions, the regions closest to the
user-defined points are retained.
Uses maxDistance for additional control.
proximity (post-filter):
- Checks the resulting faces against the original search surface
and rejects faces with a distance greater than absProximity.
ENH: restructure distance surface geometric filtering
- prefilter cells, which can be used to adjust the distance
calculation in the far field to the real distance
(not the normal distance).
This can also be used to artificially sharpen the transition
between near/far regions, if required in the future.
- generic isoSurfaceBase. Provides simpler cell-cut detection and
various functions that can be used for iso-surfaces or when
preparing prefiltered input for iso-surfaces.
- rudimentary runtime selection
ENH: isoSurface Cell/Topo uses the isoSurfaceBase infrastructure
- simpler cell cut detection, common routines
- ensure that tetMatcher is only called once per cell
ENH: use indirect patch during edge erosion
- lower overhead, allows backtracking (future) if needed
This adds a 'geometry' scheme section to the system/fvSchemes:
geometry
{
type highAspectRatio;
}
These 'fvGeometryMethod's are used to calculate
- deltaCoeffs
- nonOrthoCoeffs
etc and can even modify the basic face/cellCentres calculation.
Creates volume fields whose boundaries are used to store patch interaction
statistics.
Current field output per patch face:
- \<cloud\>\<model\>:count - cumulative particle hits
- \<cloud\>\<model\>:mass - cumuluative mass of hitting particles
Fields can be reset according to:
- none: fields are not reset
- timeStep: reset at each time step
- writeTime: reset at each write time
Usage

type patchInteractionFields;
resetMode writeTime;
}
Member function dKcdTbyKc in thermo.H is calculated from S and G at Pstd.
Thus dGdT was removed from the thermos.

- Use new thermo to multiphase solver icoReactingMuliPhaseFoam
- Remove hRefConst and eRefConst thermos.
TUT: Updated tutorials
The generalizedNewtonian viscocity models were ported from
the org version and added to the laminar turbulence framework.
This allows use in compressible and incompressible solvers
through the turbulence dictionary under the laminar sub-dictionary.
The thermal laminar viscosity is taken from the thermo for solvers
that use thermo library or from the transportProperties dictionary
for incompressible solvers.
At the moment the option to include viscocity models through the
transportDict is still available.
The icoTabulated equation of state was ported from the org version.
STYLE: use 'model' instead of 'laminarModel' in tutorials
- New solver: `acousticFoam`
- New base finite-area region class: `regionFaModel`
- New base shell model classes:
- `vibrationShellModel`

- implicitly enabled when timeStampMaster (default) is used
for the fileModificationChecking
- When running with non-distributed roots (eg, NFS-share) read for
processor directories on master only and send to sub-processes
instead individual reads.
- If disabled (old default, or when running with distributed roots),
uses the regular fileHandler readDir, which may perform readDir
on each processor. Potentially slow startup times on large systems.
Improvements based on analysis from T.Aoyagi(RIST), A.Azami(RIST)
Applies sources on turbulent kinetic energy (i.e. `k`)
and either turbulent kinetic energy dissipation rate (i.e. `epsilon`)
or specific dissipation rate (i.e. `omega`) to incorporate effects
of buoyancy on turbulence in incompressible and compressible flows.
See buoyancyTurbSource.H for details.
- was previously via inheritance, but using member data instead
supports a more flexible internal switching of the storage. It also
ensures that data access remains safe, even in the absence of
an isoSurface.
- better alignment of sampling Cell/Point/Topo inputs
- make exposedPatchName optional for isoSurface, cuttingPlane. This
was a holdover requirement from an older version of fvMeshSubset
- yields cleaner surfaces with few cuts.
Can use isoMethod keyword to select cell/point/topo if they prove
better for any particular case.
CONFIG: change default cuttingPlane algorithm from 'cell' to 'topo'
- bundles selection and control parameters used when creating
iso-surfaces. This simplifies selection and specification
- drop old compatibility handling of "cell" as a bool
- harmonize filter/regularisation flags for iso-surface
- for dictionary input, accept "isoMethod" and "isoAlgorithm" as being
synonymous. Using "isoMethod" is less subject to typing errors.
- for boundary meshes, zones etc. The behaviour with an empty matcher
was either not properly documented, and looped through all
names just to establish there was no match.
STYLE: removed redundant typedefs for point fields
- robuster matching behaviour when encountering paths that themselves
contain the word "processor" in them. For example,
"/path/processor0generation2/case1/processor10/system"
will now correctly match on processor10 instead of failing.
- use procRangeType for encapsulating the processor ranges
- provision for information of distributed vs non-distributed roots.
The information is currently available from the initial setup, but
can useful to access directly within fileOperation.
STYLE: modernize list iteration
- the NullObject singleton can also be cast to a bitSet
(sufficient size and bit-pattern). Useful for places that
need to hold a reference on construction
- (tet, pyr, hex) can be identified from their number of faces
and vertices. For these common shapes can use static `test()`
method instead of the virtual isA() method.
This is much cheaper for calling on an individual basis since
it avoids the overhead of constructing an object.
ENH: tetCell edge/reverseEdge (already had tetEdge)
- avoid potential future mistakes if someone adds a sizing dimension
and finds they have inadvertently called construct labelList with
`{std::initializer_list<label>}` instead of `label`
The if(Pstream::master()) clause in NURBS3DVolume::writeCpsInDict() was
causing the fileName of the regIOobject not to be allocated in all
processors, giving problems when masterUncollatedFileOperation::masterOp
was called by collatedFileOperation::writeObject for the mkDirOp.

- when sampling onto a meshed surface, the sampling surface may be
outside of the mesh region, or simply too far away to be considered
reasonable.
Can now specify a max search distance and default values for samples
that are too distant.
If a default value is not specified, uses Type(Zero).
Eg,
maxDistance 0.005;
defaultValue
{
"p.*" 1e5;
T 273.15;
U (-100 -100 -100);
}
- additional "names" entry to specify a word/regex list of selections
For example,
{
type patch;
name inlets;
names ("inlet_[0-9].*" inlet);
}
- if "names" exists AND contains a literal (non-regex) that can be used
as a suitable value for "name", the "name" entry becomes optional.
For example,
{
type patch;
names ("inlet_[0-9].*" inlet);
// inferred name = inlet
}

2, S1
```
The element and side number are encoded as a synthetic face id
according to
-(10 * elemId + sideNum)
but the underlying solid geometry is discarded, since there is no
reasonable way to pass it through the surface sampling mechanism.

----
install-platform: a platform (binary) installer
This is primarily driven by the need to install into system mpi
directories. The problem noted in issue #1893 is caused by the
rpm-mpi-hooks (fedora and redhat-8).
For the additional mpi library qualifier (openmpi-x86_64) to be
added to the requirements, the mpi-specific libraries (eg,
libPstream.so) need to be installed in the mpi system directory
(eg, /usr/lib64/openmpi).
However, then need symlinks from the system locations back to our
local directories to ensure that the libraries are correctly found
via our LD_LIBRARY_PATH and we don't get dummy libraries.
----
update-mpi-links: a post-install update hook
Expected paths are registered as persistent information into the
hook during packaging. Triggering the hook after installation
completes the creation of the symlinks.

- findZone(), cfindZone() to return pointer to existing or nullptr if
not found. This fits with methods such as findObject() etc for other
classes and can simplify code without checks for '-1' as not found.
- use simpler constructors for empty cell/face/point zones
- change to a templated implementation instead of relying on
the container's writeList() method.
This inlines the generation while also adding the flexibility to
define different delimiters (at compile time) without the
performance penalty of passing run-time parameters.
- deprecate get(key, deflt) in favour of lookup(key, deflt).
Method name compatibility with HashTable.
- deprecate operator().
The meaning is too opaque and equally served by other means:
- use get(key) instead of operator()(key).
Const access whereas HashTable::operator()(key)
creates missing entry.
- lookup(key, deflt) - instead of operator()(key, deflt).
Const access whereas HashTable::operator()(key, deflt)
creates a missing entry.
- make Enum iterable to allow participation in range-for etc.
- non-uniform offsets are generated due to truncation errors,
which can lead to problems later on (e.g. redistributePar).
Detect if the offsets are close to being uniform.
This also is to do with redistributePar:
this uses subsetMesh to generate parts to
send to different processors.
2) related to 1558: make sure not to choose 'mapped'
patches to move the processor patches into so
we can use the mapper cloning and correctly
size additional data (e.g. offsets). This should
be generalised to hold for any patch type
holding local data ...

The set() method originally enforce an additional run-time check
(Fatal if pointer was already set), but this was rarely used.
In fact, the set() method was invariably used in constructors
where the pointer by definition was unset.
Can now mark as deprecated to catch the last of these.

- harmonize branching logic and error handling between Function1 and
PatchFunction1.
ENH: refactor a base class for Function1, PatchFunction1

non-templated function into the correct templated selection table.

patchFaces.resize(...);
// populate patchFaces

It was observed in a MPPICDyMFoam simulation involving a single particle
in a moving mesh that the barocentric trajectory of the particle follows
an unexpected path at some arbitrary instant in time.
The issue was tracked to "hitEqn()" where cubicEqn/quadraticEqn computes
one of the roots wrongly due to the discriminant limit we set, e.g. for:
0x^3 + 1.4334549e-33 x^2 - 9.0869006e-10 x + 0.0027666538
Although the discriminant limit was carefully selected to avoid various
problems at the time, the new change is required more due to its exposition
to a wider spectrum of applications.

The main issue here was that reconstructPar is serial but coupled() in
cyclicAMIFvPatch.C could return true if both sides of the patch was present
(this->size() && neighbFvPatch().size()). However, this would result in an
evaluate call in cyclicAMIFvPatchField. This would only work if both sides
were completely contained on the same processor. The change in logic prevents
coupled() from returning true when called in serial for a decomposed case.

- also allows variants such as SYSTEMOPENMPI2 to be handled separately
ENH: provide fallback prefix for cmake detection
STYLE: simplify some shell syntax, avoid uname call in sysFunctions
STYLE: report FOAM_MPI during mpiLib builds
- no limit to the number of ways of filing ptscotch libraries.
RedHat/Fedora/CentOS should look for these directories:
ptscotch include=/usr/include/openmpi-x86_64
ptscotch library=/usr/lib64/openmpi/lib
when MPI_ARCH_PATH=/usr/lib64/openmpi
and mpicc --showme:compile yields -I/usr/include/openmpi-x86_64
- ensures that subsequent Allwmake scripts know about it.
ENH: add bin/tools/query-detect wrapper for wmake have_* scripts
CONFIG: use project/ThirdParty without additional sanity checks
- no need to test for Allwmake or platforms/ if ThirdParty is located
within the project directory itself.
COMP: add simple mpi test to 00-dummy
- for testing library linkage, etc.
- blockMesh <- extrudeModel <- dynamicMesh
COMP: bad constructor in searchableSphere
- used brace initializer instead of bracket initializer, which
triggered component-wise construction instead of copy/move
construction (gcc 4.8)
STYLE: use uint8_t instead of relying on definition of 'direction'
ENH: limit output to 25 cell types per line for readability
- makes it easier to trace potential format errors etc
STYLE: downgrade warning about polyhedrals to a simple info message
- can assume that polyhedral support is widespread enough to not
warrant a warning.
- first sort the cells into their ijk bins, and restrict testing for
face orientation to those faces with an owner or neighbour that has
an ijk bin.
ENH: ensure polyMesh from PDRblockMesh is marked as AUTO_WRITE
- the particular polyMesh constructor inherits the writeOpt, which
makes is dependent on the caller and thus somewhat fragile for the
top level caller.
- a sphere/spheroid can be specified as a single radius or three radii.
If all three values happen to be identical, they are collapsed to a
single value. Examples,
radius 2;
radius (2 2 2);
radius (2 3 4);
radius (2 2 4);
The search for nearest point on an ellipse or ellipsoid follows the
description given by Geometric Tools (David Eberly), which also
include some pseudo code. The content is CC-BY 4.0
In the search algorithm, symmetry is exploited and the searching is
confined to the first (+x,+y,+z) octant, and the radii are ordered
from largest to smallest.
Searching is optimized for sphere, prolate and oblate spheroids.
- code reduction, documentation, code stubs for spheroid (#1901)
- make searchableSurfaceCollection available as 'collection'
for consistency with other objects
- make handling of verbosity more consistent.
Make all setter return the old value, remove (unused) default
parameter as being counter-intuitive. This makes it easier to
restore the original values.
For example,
const bool oldVerbose = sampler.verbose(false);
...
sampler.verbose(oldVerbose);
- can help when designing/debugging blockMesh layouts
- propagate low-level cellModel methods face() and edge() to cellShape
STYLE: relocate blockMesh OBJ output to application only
- remove blockTopology files in cleanCase function
- improve code consistency in top-level blockMesh, PDRblockMesh
generation.
- consistent with FOAM_SIGFPE etc.
- centralize code as error::useAbort() static function to avoid
scattering the logic throughout the code.
ENH: also accept "0" and "1" string values for Switch
- not the normal path for Switch input (eg, from a dictionary), but
consistent with bool definitions and simplifies string parsing.
This means that `FOAM_SIGFPE=1 application` will now also work.
- use refPtr to simplify some logic.
- avoid copying field if an average will be used
- initialize geometric fields with a uniform value instead of Zero
- minor tweak of method names
- apply bugfix #1889 (longer description elsewhere)
- had calculated boundaries (default) for the evaluated variables,
which meant they retained their initialized values (usually Zero).
This normally goes unnoticed, since the boundary values are largely
irrelevant in the volField expressions. However, when applying
functions that balk at a zero value - eg, log() - this raises a
floating point exception.
These boundary should be zeroGradient, since the evaluated variables
correspond to the internalField only. Could continue to use
calculated, but then need to set the calculated boundary values from
the patch internal field manually.
- add -recentre option to shift points according to the bounding box
centre before performing other operations
- add -auto-origin to use the bounding box centre as the origin for
rotations. Has lower priority than the -origin option.
- surfaceTransformPoints now has distinct -read-scale, -write-scale
options (as per surfaceMeshConvert). Silently accepts -scale as
equivalent to -write-scale, for backwards compatibility and
similarity with transformPoints
- add -steps option for surfaceRefineRedGreen for successive
refinement
Allows specification of extrusion path using blockMesh 'edges' syntax.

Contribution by Ivor Clifford/Paul Scherrer Institut
ENH: add some scalar constants for .org compatibility (#1881)
Although it can very much be a moving target, it can prove partly
useful to have some compatibility constants/methods.
- The wholesale change of 'GREAT' -> 'great' etc (JAN-2018), makes
user coding for multiple versions problematic. When
COMPAT_OPENFOAM_ORG is defined, now define constants (aliases) named
as per the openfoam.org version. Values, however, remain identical.
- For type-safe dictionary value retrieval, we have the templated
get<> methods added around NOV-2018 and deprecated the lookupType
method.
The .org version followed suit in NOV-2019, but opted for renaming
the templated lookupType method as a templated 'lookup' method.
Using this is discouraged, but allowed when COMPAT_OPENFOAM_ORG is
defined.
- flips state while preserving the textual representation.
Eg, OFF <-> ON, YES <-> NO etc.
- fix test case to avoid triggering abort(), which we cannot try/catch
- provides a more direct means of generating a compound token without
an Istream
- add transferCompoundToken() without Istream reference
- mark more token methods as noexcept
- was marked as transitional/deprecated (2018-02), now deleted.
- avoids unexpected stealing of the pointer.
Use the move assignment it that is the intention.
- on ArchLinux, everything is installed under /usr/include/scotch.
The detection script uses SCOTCH_ARCH_PATH as an initial guess for
ptscotch as well. However, on the second pass, it has an absolute
value ("/usr") instead of a logical one ("scotch-system").
This resulted in the logic for handling scotch+ptscotch subdirs
being bypassed.
- the problem arises when output fields are missing on some
processors.
When the information is combined, the resulting HashTables can have
different insertion orders. This poses an issue when there are hash
key collisions and thus different chaining.
- Use sorted order.
- support construct face from subset of labels.
- additional cellModel face() method to return a single face.
- reduce some allocations in cellModel centre/mag methods
STYLE: mark old cellModeller methods as compile-time deprecated
- deprecated in 2017, but not marked as such
STYLE: indentation, spacing in some headers
- in most cases this eliminates manually calculation of circumferential
points.
TUT: improve parameterization of sphere blockMeshDict
- allow separate parameterization of radius, ratio of inner to outer,
and the number of divisions in x/y/z and radial directions
- The arc will frequently enclose an angle less than 180 degrees.
For the case, it is possible to define the arc by its endpoints
and its centre (origin) point. For example,
arc 0 1 origin (0 0 0);
When defined in the way, any discrepancy in the arc radius for the
endpoints is resolved by adjusting the origin to ensure that the
average radius is satisfied.
It is also possible to specify a \em flatness factor as a multiplier
of the radius. For example,
arc 0 1 origin 1.1 (0 0 0);
ENH: minor code cleanup for block edges
ENH: expose point appending as polyList::concat
- contents to be filled with a later assignment.
This can help avoid deduction issues when populating from a list of
tokens, and the templated version is selected:
```
template<class T>
primitiveEntry(const keyType&, const T&);
```
ENH: support construct empty ITstream with given name
- populate contents later by assigment
- provides consistency with identity(label, label) and looks more
familiar than using labelRange::labels()
- relocates labelRange IO operators to IntRange
ENH: make sliceRange interators random access
STYLE: scalarRanges::match() instead of predicate operator
- returns a range of `int` values that can be iterated across.
For example,
for (const int proci : Pstream::subProcs()) { ... }
instead of
for
(
int proci = Pstream::firstSlave();
proci <= Pstream::lastSlave();
++proci
)
{
...
}
- returns a range of `int` values that can be iterated across.
For example,
for (const int proci : Pstream::allProcs()) { ... }
instead of
for (label proci = 0; proci < Pstream::nProcs(); ++proci) { ... }
- timeVaryingUniformFixedValue -> uniformFixedValue
- allows a variety of functions (eg, coded, expressions, tables, ...)
- more similarity to finiteVolume patch type
STYLE: remove unused timeVarying... from etc/controlDict
- specifying gradientExpr without a valueExpr, a missing fractionExpr
should be treated as 0 (gradient only), not as 1 (value only)
ENH: improve sanity checks + evaluation short-cuts in exprMixedFvPatchField
- add reverse iterators and replace std::iterator
(deprecated in C++17) with full definitions
- simplify construction of iterators
- construct labelRange from a single single parameter.
This creates a (0,len) range.
- make basic constructors forms constexpr.
Remove unused size checks.
- Derive labelRange from new IntRange template class.
Allows reuse of base functionality with different integral sizes.
Deprecations:
- deprecate labelRange::valid() in favour of using
labelRange::empty() or the bool operator.
For example,
if (range) ... vs older if (range.valid()) ...
DEFEATURE: drop labelRange::null, scalarRange::null static variables
- turned out to be not particularly useful.
Can simply use constexpr contructor forms
DEFEATURE: drop labelRange::identity static method
- simply use the single-parameter constructor
1) Adding LiquidEvapFuchsKnudsen model for lagrangian evaporation.
This models is based on a diffusion type of evaporation/
condensation on particles composed of solution (liquid + solid).
2) Adding modes of calculating the particle rho and volume change.
The new keyword in constantProperties is 'volumeUpdateMethod'
which three options:
a) constantRho
b) constantVolume
c) updateRhoAndVol
The old keyword 'constantVolume' true/face is still valid
3) The entry rho0 is now optional for multicomponent parcels.
If defined , it is used, but if it is not the actual mixture
provided is used to calculate rho0 of the particle.
T0 is still used as initial T and Cp0 is over-written in the
multicomponent cloud but still required.
4) Adding tutorial for evaporation/condensation model
BUG: faMatrix::residual changes source vector (fixes#1835)
ENH: improve code alignment between faMatrix and fvMatrix
- support setValues() with a single value
- can use ListOps::appendEqOp as the more general form.
Note that this uses a different template parameter.
Eg,
`globalMeshData::ListPlusEqOp<labelList>()`
vs. `ListOps::appendEqOp<label>()`
- select default nastran PLOAD2 or PLOAD4 based on field type.
Default to PLOAD2 for scalar types and PLOAD4 for vectors etc.
- relocate nastran SHELL/MAT cards.
Previously wrote at the end of the file, now emit when writing the
geometry itself. This improves modularity (of code and files)
- initial support for common geometry file for nastran
- for CAE formats such as abaqus, nastran, starcd, etc, the element id
is already part of the output format itself. For these cases, there
is no use in generating an additional "Ids" field.
ENH: add code to ignore negative face ids
- these will arise from very special cases, such as when a
solid element and side are encoded into a single integer.
BUG: starcd surface values output did not use original face ids
- introduce WM_COMPILE_CONTROL variable to convey control information
into the build rules.
The convention (as per spack):
- '+' to select a feature
- '~' to deselect a feature
Eg, to select the gold linker, and disable openmp
(spaces are not required):
WM_COMPILE_CONTROL="+gold ~openmp"
CONFIG: accept FOAM_EXTRA_LDFLAGS for AMD, gold, Mingw linkers
CONFIG: generalize PROJECT_LIBS (-ldl used almost universally)
- originally (incorrectly) was a Field(0.0), which was generalized
to Field(Zero), but Field() is the correct form
STYLE: rename 'mustGet' to more standard 'mandatory' variable
- read header info once and reuse
- short-circuit logic to avoid unneeded checks
- additional debug information if field cannot be found
STYLE: remove unused old code remnants from #1206
- slipped in with changes to csvTableReader (commit 59ed3ba18d) so
only affects the 2006 version.
- adjust constructor to expect "componentColumns", but also accept
"valueColumns" as 1912 and earlier-compatibility. This not only
fixes the reported bug, but also ensure proper compatibility with
older files.
ENH: use "refColumn" instead of "timeColumn" for csvTableReader
- consistent with the CSV Function1.
Support 'timeColumn' as 1912 and earlier-compatibility.
TUT: remove unused table-reader entry
- experienced while reusing src/Pstream/Allwmake-mpi to create
additional mpi-layers after installation. Since the copied sources
are not located within the OpenFOAM source-tree (and/or the
source-tree is non-writable), it should not and does not use the
central build/WM_OPTIONS directory.
However, when exploring for the appropriate local Make directory, it
searched for the current '.' directory instead of checking for the
resolved directory.
This fails, since there is no src/Pstream/Make directory.
Must check for src/Pstream/mpi/Make directory first!
- Adjust wclean to always remove a local build directory
(Make/WM_OPTIONS) for additional safety.
After which, attempt to remove central build/WM_OPTIONS version too.
Script to copy/create mingw run-time installation from the Linux
cross-compilation. Packs everything into a tar or a zip file.
To accommodate Windows, all .dll files are also placed in the
platforms bin/ directory where they are easily found via the PATH.
Futhermore, ThirdParty dll files (including those from mingw itself)
are also placed in the same directory.
---
Steps
- bundles common files and directories (bin, etc, META-INFO, ...)
- copies .exe files from FOAM_APPBIN and .dll files from FOAM_LIBBIN
to the new target platforms/win64MingwDPInt32Opt/bin.
- copies mingw sys-root .dll files to the new target
platforms/win64MingwDPInt32Opt/bin
- copies other ThirdParty dll files (scotch, fftw, etc) to
platforms/win64MingwDPInt32Opt/bin
- copies tutorials (can be deactivated)
---
Note
Can only be called when the linux64Mingw environment is active.
- makes it easier to use in combination with various 'New' selectors,
which mostly return an autoPtr.
ENH: add very simple FFT test
- basic sanity test that the library links properly
- previously hidden as Detail::[IO]FstreamAllocator, now exposed
directly as [io]fstreamPointer, which allows reuse for
std::ifstream, std::ofstream wrapping, without the additional
ISstream, OSstream layers.
These stream pointers have some characteristics similar to a
unique_ptr.
- restrict direct gzstream usage to two files (fstreamPointers.C,
gzstream.C) which improves localization and makes it simpler to
enable/disable with the `HAVE_LIBZ` define.
The HAVE_LIBZ define is currently simply hard-coded in the
Make/options.
If compiled WITHOUT libz support:
- reading gz files : FatalError
- writing gz files : emit warning and downgrade to uncompressed
- warn if compression is specified in the case controlDict
and downgrade to uncompressed
ENH: minor updates to gzstream interface for C++11
- support construct/open with std::string for the file names.
CONFIG: provisioning for have_libz detection as wmake/script
- the various information queries MUST be executed with
the '--no-print-directory' or risk polluting values
in the information queries.
This is mostly seen with the 'canCompile' test for tutorials running
in parallel.
- the various information queries MUST be executed with
the '--no-print-directory' or risk polluting values
in the information queries.
This is mostly seen with the 'canCompile' test for tutorials running
in parallel.
Reduce the number of phaseSystems libraries:
- phaseSystems previously had a number of smaller libraries to provide
interface and model properties, etc. This potential flexibility was
never actually used anywhere, but causes cyclic dependencies between
phaseSystem and the models (and turbulence) that causes extreme
difficulty for mingw linking (issue #1238).
- libincompressibleMultiphaseSystems
- removed: libmassTransferModels
- libmultiphaseSystem
- removed: libcompressibleMultiphaseEulerianInterfacialModels
- libreactingMultiphaseSystem
- removed: libreactingPhaseSystem
- removed: libreactingEulerianFvPatchFields
- removed: libreactingEulerianInterfacialCompositionModels
- removed: libreactingEulerianInterfacialModels
- removed: libmultiphaseReactingTurbulenceModels
- libreactingTwoPhaseSystem
- removed: libreactingPhaseSystem
- removed: libreactingEulerianFvPatchFields
- removed: libreactingEulerianInterfacialCompositionModels
- removed: libreactingEulerianInterfacialModels
Avoid duplicate symbol for phaseCompressibleTurbulenceModels
Common turbulence models are defined in libreactingMultiphaseSystem,
and libmultiphaseReactingTurbulenceModels is now redundant.
The libtwoPhaseReactingTurbulenceModels extends the common models
for reactingTwoPhaseSystem.
- since the context (laminar/RAS/LES) is already given by the
sub-dictionary, it is redundant to use as prefix as well.
- silently support the longer names as compat methods
- old code just checked for pointer vs non-pointer.
Should actually treat CREF and REF types differently
Overseen in commit be058bec7d. Only affects develop branch
ENH: improved naming consistency in tmp, refPtr
- also use long-form to check for pointer type instead of the isTmp()
method. Makes differences between PTR, CREF, REF easier to spot.
STYLE: typeName() for tmp, refPtr is static
In fvSolution is possible to cache the limiter. This surface field
is stored in the database to be read later.
The internal tmp management of the field was not working properly.
In certain turbulence models such as kEpsilon, kOmegaSST, etc when used
in the multiphase context throw an error in the preconditioner. This
is due to alpha being zero. Fixes#1789.
- using HashPtrTable::set() with the same key twice did not guarantee
proper cleanup of memory since it simply used the underlying
HashTable::set() without doing anything about the old memory. Now
check for pre-existing storage and delete it when it does not
correspond to the newly stored pointer.
This problem is independent of potential memory slicing previously
flagged (#1286) and only partially resolved.
- naming similarity with autoPtr, unique_ptr and other containers.
For UPtrList derivatives, this is equivalent to the existing
operator(). The read-only variant is also equivalent to the
single-parameter 'set(label)' method.
With PtrList<T> list(...) :
const T* ptr = list.get(10);
if (ptr)
{
ptr->method();
}
vs.
if (list.set(10))
{
list[10].method();
}
For HashPtrTable there is only a read-only variant which is equivalent
to testing for existence and for value.
With HashPtrTable<T> hash(...) :
const T* ptr = list.get("key");
if (ptr)
{
ptr->method();
}
vs.
if (list.found("key"))
{
// Fails on null pointer!!
list["key"].method();
}
Use of get() is largely a matter of taste or local coding requirements
- forwarding like the emplace() method, but overwriting existing
entries as required
- propagate similar changes to HashPtrTable
For example, with HashPtrTable<labelList> table(...) :
With 'insert' semantics
table.emplace("list1", 1000);
vs
if (!table.found("list1"))
{
table.set("list1", new labelList(1000));
}
or
table.insert("list1", autoPtr<labelList>::New(1000));
Note that the last example invokes an unnecessary allocation/deletion
if the insertion is unsuccessful.
With 'set' semantics:
table.emplace_set("list1", 15);
vs
table.set("list1", new labelList(15));
- constructs such as the following will no longer worked, but that is
also a good thing.
ptrlist.set(i, scalarField(nFaces, Zero));
this called set(.., const tmp<scalarField>&), which meant under
the hood:
- create local temporary const scalarField&
- wrap as const tmp&
- use tmp::ptr(), to clone the const-ref
This implies an additional allocation (for the const scalarField&)
which is immediately discarded. Doubtful that compiler optimization
would do anything.
The fakeError function object emits FatalError at different stages (or
does nothing), which is useful for testing purposes (issue #1779).
Can request errors from constructor, execute and write methods.
- previously setting FOAM_ABORT would preempt checks for throwing
exceptions.
Now check for throwing first, to allow try/catch code to do its job.
However, ignore exception throwing for abort(). These are used
infrequently in the code, but indicate that recovery is deemed
impossible.
STYLE: use unique_ptr for internal stream buffer management
The function evaluate was returning true every outer loop, triggering
the re-calculation of ddt0 in every outer loop.
The evaluation of the term ddt0 should be performed once per time step.
The corrected function updates the timeIndex of ddt0 to avoid the
re-evaluation of this term in the outer loops.
- improves flexibility. Can tag a tmp as allowing non-const access to
the reference and skip additional const_cast in following code. For
example,
tmp<volScalarField> tfld(nullptr);
auto* ptr = getObjectPtr<volScalarField>("field");
if (ptr)
{
tfld.ref(*ptr);
}
else
{
tfld.reset(volScalarField::New(...));
}
auto& fld = tfld.ref();
ENH: renamed tmpNrc to refPtr
- the name 'refPtr' (reference|pointer) should be easier to remember
than tmpNrc (tmp, but non-ref-counted).
- provide tmpNrc typedef and header for code compatibility
NOTE
- in some places refPtr and tmp can be used instead of a
std::reference_wrapper for handling external references.
Unlike std::reference_wrapper, it can be default constructed
(holding nothing), whereas reference_wrapper may need a dummy
reference. However, the lifetime extension of references _may_ be
better with reference_wrapper.
- previously this was marked as '= delete' for consistency with
assignment from an empty pointer being a runtime error.
However, these can be considered semantically different and it makes
sense to permit this as equivalent to reset(nullptr).
This change does not break existing code since the operator was
previously unavailable (deleted).
STYLE: refactor tmp operator=(T*)
- delegate to reset() after initial checks
- Previously considered to be valid() if it was any reference
(null or non-null) or a non-null pointer.
This appears to be a holdover from old code (pre-2015) where
reinterpret_cast<..>(0) was used instead of the NullObject.
A reference via a null pointer isn't really possible anywhere. Even
for things like labelList::null(), they now use the NullObject,
which has a non-zero memory location.
- now simply check for a non-zero memory address. Regardless of
pointer or referenced object.
- combine reset() methods by adding a default parameter
- improve top-level visibility of empty/valid/get methods for symmetry
symmetry with autoPtr, future adjustment
- with '&&' conditions, often better to check for non-null autoPtr
first (it is cheap)
- check as bool instead of valid() method for cleaner code, especially
when the wrapped item itself has a valid/empty or good.
Also when handling multiple checks.
Now
if (ptr && ptr->valid())
if (ptr1 || ptr2)
instead
if (ptr.valid() && ptr->valid())
if (ptr1.valid() || ptr2.valid())
- This reflects the pre-existing coding situation where const_cast was
used throughout to effect the same.
STYLE: fix private/protected access
- CodedField, codedMixedFvPatchField
- libs() singleton method for global library handling
- explicit handling of empty filename for dlLibraryTable open/close.
Largely worked before, but now be more explicit about its behaviour.
- add (key, dict) constructor and open() methods.
More similarity to dimensionedType, Enum etc, and there is no
ambiguity with the templated open().
- construct or open from initializer_list of names
- optional verbosity when opening with auxiliary table,
avoid duplicate messages or spurious messages for these.
- basename and fullname methods (migrated from dynamicCode).
- centralise low-level load/unload hooks
- adjust close to also dlclose() aliased library names.
This is for a very specific use case where the faceZones are
imprinted after meshing the normal geometry. This sometimes
splits off badly connected bits of the mesh. One way to remove
these is to use e.g. subsetMesh. This embeds the
same functionality inside snappyHexMesh.
- replace `%namespace` directive with simpler `%static` directive.
We always encapsulate Lemon parser routines in an anonymous
namespace, so a simpler static linkage directive suffices.
This reduces the size of the Lemon patch (program and template).
- makes it easier to distinguish between pointers referring to pool
data versus pointers actually holding storage, avoids
manual demand-driven deletion and autoPtr.
ENH: simplify/improve Pstream profiling
- times now double (not scalar) for consistency with what cpuTime
delivers
- use bool to track suspend state
- When OpenFOAM is under git control and a 'debian/' directory exists,
this could mean two things:
1) Additional debian control has been added to OpenFOAM
2) OpenFOAM has been imported into a debian project
For the case that OpenFOAM has been imported into a debian project,
using the git information would be highly misleading. There will be no
OpenFOAM SHA1 correspondence.
However, if additional debian control has been added to OpenFOAM the
SHA1 will be valid.
The ad hoc solution is to use an additional "openfoam.debian"
directory to flag the addition of debian controls into openfoam.
When a "debian/" directory exists without a "openfoam.debian", assume
that the OpenFOAM has been imported into debian and do not use the SHA1.
- affects ensightSurfaceReader only.
If there are no `*` characters, protect against replacement.
Otherwise it would attempt to replace a zero-length string with
a single `0`, which results in prepending the name.
STYLE: ensightSurfaceReader constructor explicit
- start of work to create a 1-to-1 face mapping across AMI patches
- faces are inserted according to the AMI addressing based on Horacio's method
- removed 'updated' flag and reworked some demand driven updates
- updated to handle 'walking' through baffles
- use bitSet instead of boolList
- moved update of meshPhi to movePoints() functions at fvPatch level
- moved scaling of areas to movePoints() functions at fvPatch level
- rehomed topology change code to own file
- added warning re: geometry construction
ACMI
- split srcMask into srcMask and srcAreaMask
- former in range 0-1, and latter has bounding or tol to (1-tol) to avoid
sigFpe's
- useful for supporting a variety of different predefined
configuration files. Bypasses the regular etc/bashrc entirely.
- minor refactoring in foamCreateModuleInclude
- related to change c3571b7357 (does not affect 1912 or older).
Remnant check for data() should have used valid() method instead.
TUT: add fluxSummary cellZoneAndDirection to angledDuct/implicit
- For some cases it can be helpful to test if additional libraries can
be properly resolved.
This can be useful in scripts to test for additional capability:
if foamHasLibrary geometricVoF
then ...
fi
But also directly from the command-line to help resolve configuration
issues:
foamHasLibrary -verbose petscFoam
Could not load "petscFoam"
libpetsc.so.3.13: cannot open shared object file: No such file or directory
- when installed in-source, use PETSC_ARCH to find additional include
directory and the correct library directory
CONFIG: bump to new hypre version
- add -hint option for have_adios2, have_hypre, have_petsc
The function object now computes the acoustic pressure at a list of user
specified locations, or from the face centres of a user-supplied surface.
When operating on an input surface, the output can be written back to the
surface or as a list of point values.
Example of function object specification:
Curle1
{
type Curle;
libs ("libfieldFunctionObjects.so");
...
patches (surface1 surface2);
c0 330;
// Input - either points or surface
input points;
observerPositions ((0 0 0)(1 0 0));
//input surface;
//surface "inputSurface.obj"
// Output - either points or surface
output points;
//output surface;
//surfaceType ensight;
}
Where the entries comprise:
Property | Description | Required | Default value
type | Type name: Curle | yes |
p | Pressure field name | no | p
patches | Sound generation patch names | yes |
c0 | Reference speed of sound | yes |
input | Input type | yes |
observerPositions | List of observer positions (x y z) | no |
surface | Input surface file name | no |
output | Output type | yes |
surfaceType | Output surface type | no |
- the earlier implementation of externally controlled lumped point
motion (see merge request !120 and OpenFOAM-v1706 release notes) was
conceived for the motion of simple structures such as buildings or
simple beams. The motion controller was simply defined in terms of
an orientation axis and divisions along that axis.
To include complex structures, multiple motion controllers are
defined in terms of support points and connectivity.
The points can have additional node Ids associated with them, which
makes it easier to map to/from FEA models.

TUT: adjust building motion tutorial
- use new controllor definitions
- replace building response file with executable
- add updateControl in dynamicMeshDict for slowly moving structure
- use simpler decomposeParDict in tutorials, several had old
'boilerplate' decomposeParDict
- use simpler libs () format
- update surface sampling to use dictionary format
- Removed some unnecessary dynamicMeshDicts.
- Removed the writeActiveDesignVariables execution from the Allrun
scripts, since it is no longer necessary to execute it before
adjointOptimisationFoam.
- Updated the entries in dynamicMeshDict according to efbc9fc99.
for all objective functions.
- The normalization is useful for practically all update methods dealing
with constraints (e.g. SQP, MMA). The normalization factor can be either
given explicitly or, if not given, will be the value of the objective
function in the first optimisation cycle.
- The target value is useful when using the objective as a constraint in
constrained optimisation problems (e.g. drag - dragTarget). It should
only be used with update methods that understand the value of the
constraint (e.g. SQP, MMA) but not when the objective in hand is the
only objective of the optimisation problem. In such a case, a squared
objective should be used (e.g. sqr(drag - dragTarget))
- Objective now inherits from localIOdictionary and writes the mean
objective value under the uniform folder, each time mesh.write() is
called. This is crucial for getting the correct old merit function value
if the simulation is continued from a previous state and lineSearch is
used.
- Objectives are now computed and written even if the corresponding
adjoint solver is inactive. This, among others, is also essential for
getting the correct old merit function value in case of continuation.
- Writing of the objective function (and its mean, if present) history
has now moved to updatePrimalBasedQuantities, instead of the preLoop
part of the adjoint solvers. This was decided to get the objective
values to files, even if the adjoint solver is inactive. Arguably, an
even better place to write the objective functions would be the postLoop
part of the primal solvers, however this might cause multiple writes of
the objective value for the inner iterations of lineSearch, if one is
used.
Moved part common to all derived classes (e.g. update) to the base
class to avoid code duplication. Practically, only the protected
updateDesignVariables has to be overwritten in each derived class now.
steadyOptimisation was also affected in a minor way.
- Added function returning the underlaying surface sensitivities
- Added boolean to control whether to write the underlaying sensitivity
map (defaults to false)
Encapsulates all terms that are common in both E(SI) and FI
formulations, like direct sensitivities and sensitivities due to
primal boundary conditions. Added the latter to all derived sensitivity
types, except for sensitivity maps.
Same as adjointWallVelocity but also returns the contribution
of the differentiation of the rotatingWallVelocity BC wrt the
face centres, to be added to the sensitivity derivatives.
Main reason was the insertion of a templated virtual function
returning the contribution of the differentiation of the primal
boundary condition, in the case the latter directly depends on a
a geometric quantity (e.g. rotatingWallVelocity).
Example usage:
removeParcels1
{
type removeParcels;
log yes;
resetOnWrite no;
resetOnStart no;
faceZones (cycLeft cycRight);
}
Number and mass of particles removed are written to file
to geometricVoF
sampledInterface was linked to interfaceProperties thorugh geometricVoF,
and interfaceProperties created a conflict on surfaceTension table
when linked in the reactingEuler solvers by the sampling lib
Example usage:
cloudFunctions
{
WeberNumber1
{
type WeberNumber;
}
}
This will calculate and write the Weber number field as a 'standard'
cloud field, available for post-processing alongside other lagrangian
fields in the lagrangian/<cloudName> directory.

- missing minThreshold in activePressureForceBaffleVelocity
- update names of cyclics
- increase tolerance for zero-thickness baffles

(drive separator)
- apply similar local change for the momentum function object.
*** This topic will be revisited in the future ***
- overrides normal deltaT for testing accelerated motion.
Can be useful to test mesh motions with constant/dynamicMeshDict
entries (updateControl, updateInterval) where the mesh motion is
much slower than any of the fluid physics.

\endverbatim
The integration of the code was carried out by Andy Heather and Sergio
Ferraris from OpenCFD Ltd.
ENH: update libs of etc/caseDicts/postProcess items
ENH: ensure destructor=default
ENH: ensure constness
ENH: ensure no 'copy construct' and 'no copy assignment' exist
TUT: add examples of function objects with full set
of settings into a TUT if unavailable
TUT: update pisoFoam/RAS/cavity tutorial in terms of usage
The PIMPLE option finalOnLastPimpleIterOnly allows the call the Final
solver only in the last PIMPLE loop. The default is false which is
the present behavior.
- When compiling additional modules or user code, we need more control
for the installation locations beyond the usual FOAM_USER_LIBBIN,
FOAM_SITE_LIBBIN, FOAM_LIBBIN, and wish to have these values be
modifiable without editing files.
- provide wmake rules for handling standard defaults:
* GENERAL_RULES/module-path-user
* GENERAL_RULES/module-path-group
* GENERAL_RULES/module-path-project
which are incorporated as follows:
Make/options:
include $(GENERAL_RULES)/module-path-user
Make/files:
LIB = $(FOAM_MODULE_LIBBIN)/libMyLibrary
By default these would compile into FOAM_USER_{APPBIN,LIBBIN} but
could be adjusted at compilation time. For example,
```
wmake -module-prefix=/path/my-install-location
```
Or
```
./Allwmake -module-prefix=/path/my-install-location
./Allwmake -prefix=/path/my-install-location
```
Or
```
FOAM_MODULE_PREFIX=/path/my-install-location ./Allwmake
```
ENH: add -no-recursion option for AllwmakeParseArguments
- more descriptive naming than the -fromWmake option (still supported)
- remove wmake/scripts/wmake.{cmake,wmake}-args since the -prefix
handling and -no-recursion is now directly handled by AllwmakeParseArguments
- now list compiler versions in reverse order (newest first) similar
to how they are listed on the gcc/llvm sites. Add comments to
mention which compiler series are now considered unsupported.
ENH: add generalised log-law type ground-normal inflow boundary conditions for
wind velocity and turbulence quantities for homogeneous, two-dimensional,
dry-air, equilibrium and neutral atmospheric boundary layer (ABL) modelling
ENH: remove `zGround` entry, which is now automatically computed
ENH: add `displacement height` entry, `d`
ENH: add generalised atmBoundaryLayerInletOmega boundary condition
ENH: add a verification case for atmBoundaryLayerInlet BCs
DOC: improve atmBoundaryLayerInlet header documentation
BUG: fix value-entry behaviour in atmBoundaryLayerInlet (fixes#1578)
Without this change:
- for serial-parallel computations, if `value` entry is available in
an `atmBoundaryLayerInlet` BC, the theoretical ABL profile expressions
are not computed, and the `value` entry content is used as a profile data
- for parallel computations, if `value` entry is not available, `decomposePar`
could not be executed.
With this change:
- assuming `value` entry is always be present, the use of `value` entry for
the ABL profile specification is determined by a flag `initABL`
- the default value of the optional flag `initABL` is `true`, but whenever
`initABL=true` is executed, `initABL` is overwritten as `false` for the
subsequent runs, so that `value` entry can be safely used.
Thanks Per Jørgensen for the bug report.

TUT: update simpleFoam/turbineSiting tutorial accordingly
STDMD (i.e. Streaming Total Dynamic Mode Decomposition) is a variant of
a data-driven dimensionality reduction method.
STDMD is being used as a mathematical post-processing tool to compute
a set of dominant modes out of a given flow (or dataset) each of which is
associated with a constant frequency and decay rate, so that dynamic
features of a given flow may become interpretable, and tractable.
Among other Dynamic Mode Decomposition (DMD) variants, STDMD is presumed
to provide the general DMD method capabilities alongside economised and
feasible memory and CPU usage.
Please refer to the header file documentation for further details.
ENH: add new STDMD tutorial, pimpleFoam/laminar/cylinder2D
ENH: add Test-EigenMatrix application
The new iterative eigen decomposition functionality is
derived from:
Passalacqua et al.'s OpenQBMM (openqbmm.org/),
which is mostly derived from JAMA (math.nist.gov/javanumerics/jama/).
- generates a vtk file in an ASCII, XML format (blockTopology.vtu).
More information than the equivalent obj file since it includes
connectivity, cell shapes and cell IDs (equivalent to the block
numbers).
- new vtk::internalMeshWriter, vtk::patchMeshWriter
intermediate classes without finiteVolume dependencies.
Enables direct use with a polyMesh.
Makes vtk::internalWriter, vtk::patchWriter header/template only.
- bundled of boolean values as a vector of 3 components with
element access using x(), y() and z() member functions.
It also has some methods similar to bitSet.
- Not derived from Vector or VectorSpace since it does not share very
many vector-like characteristics.
- support construct from initializer_list, which can help simplify
code with constant coefficients.
- add default constructor for polynomialFunction and Istream reading
to support resizable lists of polynomialFunction.
A default constructed polynomialFunction is simply equivalent to
a constant zero.
- no special IO handling for Polynomial required,
it is the same as VectorSpace anyhow.
The phase systems tables for multiphase solvers create conflict
between each other as they are defined in the same namespace and using
similar class names.
Therefore a special htc function object for reactingEulerSolver was
added (reactingEulerHtcModel), located under
src/phaseSystemModels/reactingEulerFoam/functionObjects/
This commit includes the following:
- Relocate solvers/reactingEulerFoam functionObjects to
src/phaseSystemModels
- Remove links for fieldFunctionObject to multiphase libs to avoid
conflicts
- New FO for htc for reactingEulerFoam called reactingEulerHtcModel
- previously introduced `getOrDefault` as a dictionary _get_ method,
now complete the transition and use it everywhere instead of
`lookupOrDefault`. This avoids mixed usage of the two methods that
are identical in behaviour, makes for shorter names, and promotes
the distinction between "lookup" access (ie, return a token stream,
locate and return an entry) and "get" access (ie, the above with
conversion to concrete types such as scalar, label etc).
- Favour use of argList methods that are more similar to dictionary
method names with the aim of reducing the cognitive load.
* Silently deprecate two-parameter get() method in favour of the
more familiar getOrDefault.
* Silently deprecate opt() method in favour of get()
These may be verbosely deprecated in future versions.
- before (-lreactingPhaseSystem -ltwoPhaseReactingTurbulenceModels)
after (-ltwoPhaseReactingTurbulenceModels -lreactingPhaseSystem)
to fix symbol resolution issue on clang.
- similar to the behaviour of std::ignore and consistent with the
no input / no output nature of nullObject. Similarly accept a
const reference for its Istream operator.
- make most nullObject methods constexpr
- mostly wraps std::chrono so can inline much of it, which is potentially
helpful when used for inner timings.
- add elapsedTime() method for direct cast to double and for
naming similarity with wall-clock method.
Potential breaking change (minor):
- clockValue construct with a bool parameter is now simply tagged
dispatch (value is ignored) and always queries the current clock
value. This avoids needless branching.
Since this constructor form has primarily been used internally (eg,
clockTime), breakages in user code are not expected.
- have printBuildInfo output to std::ostream
- removed extraneous include "stdFoam.H"
ENH: revert to pre-processor defines for hard-coded paths (#1712)
- redundant information, but more robust at run-time without relying
on initialization order
- previously could only run from the project directory
- strip surrounding double quotes on input of path names
since they are added automatically when editing.
- previously relied on presence/absence of command-line options.
Can now explicitly disable individually
- provide shorter constructors for dealing with these types of cases.
Make construction with non-default names for "system" and "constant"
lengthier so there is no ambiguity.
multiphaseReactingTurbulenceModels and twoPhaseReactingTurbulenceModels
add models to the same table TurbulenceModel. These two libs were removed
from libreactingPhaseSystem which created the conflict.
The multiphaseReactingTurbulenceModels was added to
reactingMultiPhaseEulerFoam solver and twoPhaseReactingTurbulenceModels to
twoPhaseReactingEulerFoam solver
The FO heatTransferCoeffs for libfieldFunctionObjects needs
twoPhaseReactingTurbulenceModels.
These change avoids linking conflict from multiphaseReactingTurbulenceModels
and twoPhaseReactingTurbulenceModels being linked in the same lib.
- Provide Allwmake-mpi scripts for handling the MPI-only build segment.
- Adjust Make/options to support a FOAM_MPI_LIBBIN target location.
This will simply default to FOAM_LIBBIN/FOAM_MPI, but allows different
types of builds with out-of-tree targets.
Example,
Build OpenFOAM with default MPI settings (eg, system openmpi)
```
./Allwmake
```
Rebuild MPI-layers with different MPI.
For any given and known type
```
othermpi()
{
export WM_MPLIB=OPENMPI
export FOAM_MPI=openmpi-3.1.3
export OPAL_PREFIX=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER/$FOAM_MPI
export MPI_ARCH_PATH="$OPAL_PREFIX"
}
```
May wish to build/rebuild ptscotch
```
(
othermpi
$WM_THIRD_PARTY_DIR/makeSCOTCH
)
```
Rebuild the mpi-dependent parts. Can also provide install location
```
for script in $(find src -name Allwmake-mpi)
do
(
other_mpi
export FOAM_MPI_LIBBIN="$HOME/tmp/install-prefix/lib/$FOAM_MPI"
)
done
```
The final leak can only be decided once all cells have been
deleted. So only exit on final invocation and give warning-only
beforehand. This avoids a lot of false positives.
The tutorial itself didn't actually produce a mesh with leakage
with the old settings. Upped the refinement level to force it
to go through the hole in the geometry.
- scripts/wmake.wmake-args partial logic for Allwmake scripts.
- handle '-quiet' as synonym for '-silent'
- Do not specify '-j' option for wrapped cmake creation to avoid
the warning:
make[1]: warning: -jN forced in submake: disabling jobserver mode.
ENH: defaulting for destructors where possible
STYLE: clear() instead of setSize(0) for plain Lists
STYLE: use bool operator instead of valid()/empty() for autoPtr tests
- enumerated values are (points | topology) which can be optionally
specified in the blockMeshDict. Default is 'topology'.
If the command-line option `blockMesh -merge-points` is specified,
this has absolute priority over any blockMeshDict entry.
STYLE: changed blockMesh "-blockTopology" option to "-write-obj"
- this is more specific to what it does. Potentially wish to add a
"-write-vtk" option in the future.
TUT: adjust tutorials to use preferred or necessary merge strategies:
* channel395DFSEM - topology
* nozzleFlow2D - points
* pipeCyclic - points
- dependency handling relocated from cmakeFunctions to wmakeFunctions
and reused for mpi-versioned builds. This allows more checks for
configuration parameters and removes hard-code build path
information.
CONFIG: remove spurious mplibHPMPI entries
CONFIG: remove ADIOS1 rules (antiquated)
- initial split of wmake-related commands into "plumbing" and
"porcelain" akin to how git handles things.
- wmakeBuildInfo (very low-level), now relocated to the wmake/scripts
and accessible for the user as "wmake -build-info".
This satisfies a long-standing desire to access build information
in a fashion similar to the api/patch information.
CONFIG: avoid git information when building with a debian/ directory
- when a 'debian/' directory exists, there is a high probability that
the '.git/' directory is from debian and not from OpenFOAM (ie,
useless here). This corresponds to an implicit '-no-git', which has
no effect when building from pristine sources.
ENH: wmakeCheckPwd becomes scripts/wmake-check-dir
- accessible for the user as "wmake -check-dir" and with 1 or 2
directory names. A wmakeCheckPwd symlink left for compatibility.
- less frequently used, but the information was previously inaccessible
under etcFiles.C.
Now exposed within the foamVersion namespace and defined under
<global.Cver> to improve configuration possibilities.
- convenient way to use alternative plugin installations
- provide separate -help-build information and reduce the noisy output
when a reader module cannot be located.
- adds into the include-quoted search list instead the general (-Idir)
search list.
* makes it less subject to ordering (since it will now generally be
searched first) and makes it less subject to how duplicate removal
is implemented. In some compilers (#1627), the last instance of
a duplicate directory would be used and not the first instance.
* removes clutter in some Make/options files
COMP: add missing linkage libraries
- improve handling of changes in ParaView/VTK or cmake parameters (#1693)
* adjust internals to support recording of an unlimited number of
configuration parameters and use file `cmp` instead of trying
to check strings ourselves.
ENH: new wmake/scripts/wmake.cmake-args handler
- additional handling of -prefix=... as CMAKE_INSTALL_PREFIX export.
- in some contexts, can use instead of AllwmakeParseArguments
- this specifically arises in the case we have used the `#eval` syntax
to generate a value.
However, since the expressions produce scalar/vector/tensor etc, the
tokenized value will *not* be introduced into the dictionary as a
label, even if it appears to be an integer value.
Eg, eval "2*5", eval "sqrt(100)" both yield `scalar(100)`, which
will not be suitable for any consumer expecting a label value.
With the `#calc` version, this problem is glossed over since it uses a
string buffer for the output (which can suppress the decimal)
and re-parses the string into tokens, which causes a label to be
recognized.
- Since we obviously already support implicit handling of ints as
floats (when reading), now also allow conversion of float
representations of integral values.
Uses the ad hoc value of 1e-4 for deciding if the value deviates too
far from being integral.
- As a side-effect, can now also support scientific notation when
specifying integers. Eg, (10 100 1e+3) for cell counts.
- simplified templating, which cleans up code and does not appear to
break any normal user coding.
ENH: unique_ptr instead of homegrown demand-driven handling.
For a given point within a given mesh, the existing `meshWave` method gives
the orthogonal distance to a patch. In meshes with very steep terrain (e.g.
a hill of 90 [deg], this might be problematic for the fields that require
the distance to the patch associated with the terrain surface.
`directionalMeshWave` is a variant of `meshWave` distance-to-patch method,
which ignores the component in the specified direction. Can be used e.g. to
calculate the distance in the z-direction only.
TUT: add example of directionalMeshWave to mesh/moveDynamicMesh/SnakeCanyon
Requirement by CENER
Implementation by Mattijs Janssens
- takes a search string and a replacement character.
The replacement character can also be a nul char ('\0'), which
simply removes the characters.
Possible uses:
* Replace reserved characters
str.replaceAny("<>:", '_');
* Remove shell meta-characters or reserved filesystem characters
str.replaceAny("*?<>{}[]:", '\0');
- construct from dimensioned/value, defaulting name from value.
Can be convenient for these type of operations:
max(.., dimensionedScalar(somedims, 0.5))
- construct from dimensioned/one, forwarding to pTraits::one.
Can be convenient for constructors:
volScalarField( ..., dimensionedScalar(somedims, one{}))
ENH: minor updates to zero/one classes.
- add global 'One' constant for symmetry with 'Zero'.
- clearer than passing a reference to a dummy variable,
or relying on move occuring within the copy constructor
(historical, but should be deprecated)
STYLE: consistent autoPtr syntax for uncollated file operations
- can help in circumstances when an zero-sized entry is written on
some processors, but the compound-type may be useful for determining
a particular code path when re-reading the files. Ensures that the
information is consistent on all processors.
STYLE: adjust separation of includes between List.H and UList.H
- bin/tools/create-mpi-config to query/write values for system openmpi.
In some cases this can be used to avoid an mpicc requirement at runtime.
- adjust openfoam session to include -test-tutorial forwarding to the
tutorials/AutoTest. This helps with writing installation tests.
- adjust foamConfigurePaths to latest version
- removal of gperftools default config, as per develop
1) Add interfaceHeatResistance model to icoReactingMultiphaseInterFoam
This model uses a spread source for the continuity Eq.
It is recommended for cases with good mesh resolution.
2) Adding iso-surface type of calculation for the interface for
the kineticGasEvaporation model
3) Add switch for option to take into account volume change
4) Add poolEvaporation tutorial
- remove MSWindows components (code and makefiles)
- use cxx, hxx extensions to reduce possible confusion with other
"list" and "vector" classes
- use C++ versions for C headers
- align wmake have_* scripts to support version query as per current
develop branch
- use config.sh/ fallbacks when the corresponding *_ARCH_PATH is empty
(eg, BOOST, CGAL, FFTW).
This aids when building outside of the regular OpenFOAM environment.
- add '[-+.~]' to the recognized qualifiers.
This allows simple readable names such as
WM_COMPILER=Clang-vendor
but also opens the FUTURE (not yet supported) possibility of
combining in additional information. For example,
WM_COMPILER=Clang~openmp
WM_COMPILER=Clang+cuda~openmp
by using '+' (add) and '~' (subtract) notation similar to what
spack uses.
CONFIG: support 'override' rules
- if present, compiler-family 'override' rules are included after
compiler-family 'general' rules have been included. This allows a
central means for including dynamically generated content to
override some values.
Some examples:
To handle different gcc versions (system compiler):
wmake/rules/...Gcc/override
```
ifneq (,$(findstring 9, $(WM_COMPILER)))
cc := gcc-9
CC := g++-9 -std=c++11
endif
```
To handle different openmp on Darwin (#1656):
wmake/rules/darwin64Clang/override
```
# Use libomp (not libgomp) unless openmp is disabled
ifeq (,$(findstring "~openmp", "$(WM_COMPILER)"))
COMP_OPENMP = -DUSE_OMP -Xpreprocessor -fopenmp
LINK_OPENMP = -lomp
else
include $(GENERAL_RULES)/no-openmp
endif
```
This treatment arguably fits into wmake/rules/darwin64Clang/general,
but it serves to illustrate a possible use case.
1) The sign of radiative flux (qr) for modes Power and HeatFlux was
corrected.
2) Relaxation factor implementation was incomplete. Now caching
valueFraction and refValue from the previous time step.
- use Clang instead of Gcc for Darwin since this is its system
compiler. The user can force use of Gcc by using Gcc92 etc.
- make etc/cshrc sed check more robust.
- replace tcsh (${%var}) syntax with ("${var}" != "")
[Fixes and ideas from Alexey Matveichev]
CONFIG: do not source the gperftools environment by default
- this is now an used feature, but can be re-enabled by advanced users
if required.
- as a side-effect of recent changes, command-line stripping of .gz
extensions on input was lost. For example,
OK: surfaceTransformPoints file.stl ...
Fail: surfaceTransformPoints file.stl.gz ...
- restore the previous behaviour of silently stripping the '.gz'
extension on input.
ENH: add triSurface::New selector entry point
- for symmetry with MeshedSurface
Now the thermal baffle can be extrapolated from a patch which is
coupled to the bottom patch of the solid region.
The user can set the T bc on the 'top' patch of the solid.
The new keyword is 'internal' and its default is true. Check new
tutorial for an example:
tutorials/heatTransfer/buoyantSimpleFoam/roomWithThickCeiling/
- reads/write shell elements
Output elements are "bunched" according to type and their set
without reordering.
- preliminary reading of solids without extraction.
Handling of *Surface specifications is not implemented
- enhancement and potential breaking change.
Nastran surface writer previously used the keyword 'scale' for
field scaling, which was applied uniformly to all output fields.
Change the meaning of 'scale' to be geometric scaling
(consistent with reading triSurfaceMesh etc).
New 'fieldScale' entry is an optional dictionary of scaling
parameters.
Example,
nastran
{
scale 1000; // [m] -> [mm]
fieldScale
{
"p.*" 0.01; // [Pa] -> [mbar]
}
}
- adjustments to internal handling to improve run-time addition of
other formats (eg, with additional user library)
For example, to write a binary STL with a '.stl' extension:
$ surfaceMeshConvert input.obj -write-format stlb output.stl
Or in a sampler,
to specify the input type without ambiguity:
surf
{
type meshedSurface;
surface sampling.inp;
fileType starcd;
scale 0.001;
...
}
STYLE: regularize naming for input/output scaling
* -read-scale (compat: -scaleIn)
* -write-scale (compat: -scaleOut)
CONFIG: change edge/surface selection name for STARCD format
- now select as "starcd" instead of "inp" to avoid naming ambiguity
with abaqus
- had a PrimitivePatch with SubField, but now use const pointField&.
There is no derivation path from a pointIOField to SubField<point>,
so a const reference makes more sense.
- face_type, point_type (similar to STL value_type, etc).
The naming avoids potential confusion with template parameters.
- rename private typedef from ParentType to MeshReference for more
consistency with polySurface etc.
- regression introduced by 431c9632f9
The triSurface dictionary constructor applies the scaling,
and thus it can be reported, but not applied in triSurfaceMesh
- previously used a Pstream::exit() invoked from the argList
destructor to handle all MPI shutdown, but this has the unfortunate
side-effect of using a fixed return value for the program exit.
Instead use the Pstream::shutdown() method in the destructor and allow
the normal program exit codes as usual. This means that the
following code now works as expected.
```
argList args(...);
if (...)
{
InfoErr<< "some error\n";
return 1;
}
```
- preferentially handle Allwmake.override, which allows packaging
tools to define alternative make scripts, or selectively disable
components.
- remove legacy handling of 'Optional' directory.
Conditionals have since migrated into scripts themselves and/or
use the wmake/scripts/have_* framework.
BUG: missed passing -debug for Allwmake scripts
- missed detection of system libraries when installed with multiarch
paths like /usr/lib/x86_64-linux-gnu
CONFIG: improve handling of group/user config files (#928)
- changed bashrc handling of FOAM_CONFIG_NOUSER to use
FOAM_CONFIG_MODE instead. Propagate into foamEtcFile to make this
a stickier control.
This change allows better control, but also enables cluster
installations to define their own value within the OpenFOAM prefs.sh
file to prevent users accidentally mis-configuring things if
necessary.
- remove undocumented handling of an (a)ll mode in foamEtcFile to
avoid potential pitfalls.
- add support for FOAM_CONFIG_ETC handling.
This allows injection of an extra search layer when finding
project etc files
ENH: improvements to foamConfigurePaths (#928)
- handle FOAM_CONFIG_ETC implicitly, or explicitly with the new
-etc option.
STYLE: more explicit wording in foamConfigurePaths usage (#1602)
- document that an absolute path (eg, -scotch-path) overrides/ignores
the equivalent ThirdParty setting (eg, -scotch)
- longer options -system-compiler and -third-compiler for -system
and -third, respectively. Clearer as to their purpose.
- adjust the location sanity check to look for META-INFO directory.
- '-c' option (as per shell), '-Dkey[=value]' option to provide
preferences via the command-line. For example,
etc/openfoam -DWM_COMPILER=Clang -int64 ./Allwmake -j -s -l
These can also be combined with other options. Eg,
etc/openfoam -DWM_COMPILER=Clang \
-c 'wmake -show-path-cxx -show-cxxflags'
- relocated from bin/tools/ => etc/ for easier access
- bin/tools/openfoam.in : for autoconfig-style installation
- Auto-detect if the shell script was executed with openfoam and
interpret accordingly.
Simple example,
--------------
#!/usr/bin/openfoam
cd "${0%/*}" || exit # Run -*-sh-*- from this dir
blockMesh
simpleFoam
--------------
Note it is NOT currently possible to provide any other parameters
this way. Eg,
`#!/usr/bin/openfoam -sp` (NOT)
This will either fail to run, or result in infinite recursion.
- base level surface container is now a meshedSurface instead of
a triSurface. This avoid automatic triangulation of surfaces
when they are read, and simplifies the internals.
- sampling types:
* "meshedSurface" (compat: "sampledTriSurfaceMesh")
* "meshedSurfaceNormal" (compat: "sampledTriSurfaceMeshNormal")
- uses MeshedSurface instead of triSurface to prevent automatic
triangulation.
- supports '-patches' and '-excludePatches' controls as per foamToVTK.
For example,
surfaceSplitByPatch -patches '( ".*rider.*" )' motorBike.obj
ENH: use MeshedSurface for surfaceSubset
- removed swapZones method (unused, potentially fragile)
- add subsetMesh by name
BUG: incorrect zone assignment in MeshedSurface::subsetMesh
- used the new (zero-sized) zone when determining the old zone ending
instead of the original zone bounds.
- refactor logic from triSurfaceMesh for triSurface, MeshedSurface,
UnsortedMeshedSurface.
Makes it easier to locate and use surface files without the
triSurfaceMesh (meshTools) infrastructure.
STYLE: remove unused sampledTriSurfaceMesh constructors
Often we want to copy a field and replace boundary conditions, e.g. change type
to calculated for some patches. This has typically been achieved by creating a
word list of new patch types which are then fed through to the fvPatchField::New
factory method. This is OK for types that require no additional input (usually
from dictionary) but leaves other more complex types partially
constructed/usable.
The new constructor clones all BCs except those with indices specified, for
which the fvPatchField::New method is called for the supplied patch field type.
- avoid face copying.
Maintain separate offsets/list for non tri/quad face decomposition,
which eliminates copying for tri/quad types that represent the bulk
of geometries
- report inappropriate use of PLOAD2 for higher-ranks only once per
field instead of per face. For this case, write its magnitude
instead of 0.
- perform field output scaling prior to calling the write face
function. This will make it easier to handle different per-field
scaling in the future (#1612)
BUG: nastran quad written as "CTRIA3" instead of "CQUAD4"
- missed detection of system libraries when installed with multiarch
paths like /usr/lib/x86_64-linux-gnu
CONFIG: improve handling of group/user config files (#928)
- changed bashrc handling of FOAM_CONFIG_NOUSER to use
FOAM_CONFIG_MODE instead. Propagate into foamEtcFile to make this
a stickier control.
This change allows better control, but also enables cluster
installations to define their own value within the OpenFOAM prefs.sh

- remove undocumented handling of an (a)ll mode in foamEtcFile to
avoid potential pitfalls.
- add support for FOAM_CONFIG_ETC handling.

project etc files
ENH: improvements to foamConfigurePaths (#928)
- handle FOAM_CONFIG_ETC implicitly, or explicitly with the new
-etc option.

- document that an absolute path (eg, -scotch-path) overrides/ignores
the equivalent ThirdParty setting (eg, -scotch)
- longer options -system-compiler and -third-compiler for -system
and -third, respectively. Clearer as to their purpose.
- adjust the location sanity check to look for META-INFO directory.
- string expansions have supported "${var:-default}" syntax for
several versions, but this did not apply plain dictionary expansions.
Eg, the following did not parse
massFlow ${entry1:-100};
ENH: remove content and length restriction on '${..}' quoted variables
- allows this type of content:
velocity2 ${velocity1:- ( 0 -100 10) };
- accept empty parameter strings for entries. This allows the
following expansion to work as expected:
hex (n1 n2..) ${inletBlock:-} (10 10 10) simpleGrading (1 1 1)
ie, optionally define the cellZone name for a given block
ENH: add single parameter dictionary writeEntry method.
- the dictionary knows its own name (dictName), which can be used
when writing content
Style changes:
- use std algorithm for some stringOps internals
- pass SubStrings iterators by const reference
ENH: special nullptr handling for ISstream getLine
- pass through to istream::ignore to support read and discard
1) Adding interfaceHeight FO
2) Adding interfaceHeatResistance mass transfer model to
interCondensatingEvaporatingFoam with spread source approach
3) Reworking framework for icoReactingMultiphaseInterFoam
* Support default values for format/compress enum lookups.
- Avoids situations where the preferred default format is not ASCII.
For example, with dictionary input:
format binar;
The typing mistake would previously have caused formatEnum to
default to ASCII. We can now properly control its behaviour.
IOstream::formatEnum
(
dict.get<word>("format"), IOstream::BINARY
);
Allowing us to switch ascii/binary, using BINARY by default even in
the case of spelling mistakes. The mistakes are flagged, but the
return value can be non-ASCII.
* The format/compression lookup behave as pass-through if the lookup
string is empty.
- Allows the following to work without complaint
IOstream::formatEnum
(
dict.getOrDefault("format", word::null), IOstream::BINARY
);
- Or use constructor-like failsafe method
IOstream::formatEnum("format", dict, IOstream::BINARY);
- Apply the same behaviour with setting stream format/compression
from a word.
is.format("binar");
will emit a warning, but leave the stream format UNCHANGED
* Rationalize versionNumber construction
- constexpr constructors where possible.
Default construct is the "currentVersion"
- Construct from token to shift the burden to versionNumber.
Support token as argument to version().
Now:
is.version(headerDict.get<token>("version"));
or failsafe constructor method
is.version
(
IOstreamOption::versionNumber("version", headerDict)
);
Before (controlled input):
is.version
(
IOstreamOption::versionNumber
(
headerDict.get<float>("version")
)
);
Old, uncontrolled input - has been removed:
is.version(headerDict.lookup("version"));
* improve consistency, default behaviour for IOstreamOption construct
- constexpr constructors where possible
- add copy construct with change of format.
- construct IOstreamOption from streamFormat is now non-explicit.
This is a commonly expected result with no ill-effects
- align Switch more with Enum.
Now have find(), found() static methods.
Constructors with failsafe option.
The find() method makes for clearer coding:
OLD
Switch sw(some_string, true); // NB: true = allowBad
if (sw.valid()) ...
NOW
Switch sw = Switch::find(some_string);
if (sw.good()) ...
or
if (Switch::found(some_string)) ...
- improve construct from dictionary to handle all valid token types.
Previously just read in a word.
- Remove asText() method - replaced by c_str() and str() several
versions ago.
- renamed 'core/' -> 'base/' to avoid gitignore masking when re-adding
files
- rename 'nas/' to 'nastran/' for more clarity
- relocated OBJstream from surfMesh to fileFormats
STYLE: remove unused parseNASCoord. Was deprecated 2017-09
- `tensor` and `tensor2D` returns complex eigenvalues/vectors
- `symmTensor` and `symmTensor2D` returns real eigenvalues/vectors
- adds new test routines for eigendecompositions
- improves numerical stability by:
- using new robust algorithms,
- reordering the conditional branches in root-type selection
- In the course of time, global funcs/opers of Tensor types expanded
leaving funcs/opers unordered.
- Therefore, by following the order designated in Matrix class, the order
of global funcs and global opers are reordered:
- oper+ oper- oper* oper/ inner-product double-inner-product outer-product
- ensures each Tensor-container operates for the following base types:
- floatScalar
- doubleScalar
- complex
- adds/improves test applications for each container and base type:
- constructors
- member functions
- global functions
- global operators
- misc:
- silently removes `invariantIII()` for `tensor2D` and `symmTensor2D`
since the 3rd invariant does not exist for 2x2 matrices
- fixes `invariantII()` algorithm for `tensor2D` and `symmTensor2D`
- adds `Cmpt` multiplication to `Vector2D` and `Vector`
- adds missing access funcs for symmetric containers
- improves func/header documentations
- includes restructuring and simplification of low-level ensight part
handling and refactor of backends to improve code reuse.
foamToEnsight
-------------
* new cellZone support.
This was previously only possible via a separate foamToEnsightParts
utility that was not parallelized.
* support for point fields.
* `-nearCellValue` option (as per foamToVTK)
* data indexing now uses values from the time index.
This is consistent with the ensightWrite function object and
can help with restarts.
* existing ensight directories are removed, unless the -no-overwrite
option is supplied
foamToEnsightParts
------------------
* now redundant and removed.
ensightOutputSurface (new class)
--------------------------------
* a lightweight wrapper for point/face references that is tailored
for the ensightSurfaceWriter. It uses compact face/point information
and is serial only, since this is the format requirements from the
surfaceWriter class.
ensightMesh (revised class)
---------------------------
* now only holds a polyMesh reference, which removes its dependency
on finiteVolume and allows it to be relocated under fileFormats
instead of conversion.
Removed classes: ensightParts, ensighPartFaces, ensightPartCells
- these were used by foamToEnsightParts, but not needed anymore.
- incorrectly set BINARY format in the construction of the received
data (a side-effect of the parameter ordering).
Now use the same default parameters as IFstream and set the correct
filename subsequent to construction.
- '-c' option (as per shell), '-Dkey[=value]' option to provide
preferences via the command-line. For example,
etc/openfoam -DWM_COMPILER=Clang -int64 ./Allwmake -j -s -l
These can also be combined with other options. Eg,
etc/openfoam -DWM_COMPILER=Clang \
-c 'wmake -show-path-cxx -show-cxxflags'
- relocated from bin/tools/ => etc/ for easier access
- bin/tools/openfoam.in : for autoconfig-style installation
- Auto-detect if the shell script was executed with openfoam and
interpret accordingly.

blockMesh
simpleFoam
--------------
Note it is NOT currently possible to provide any other parameters
this way. Eg,
`#!/usr/bin/openfoam -sp` (NOT)
This will either fail to run, or result in infinite recursion.
- simplifies code, covers most cases.
Can use wmake -show-api or wmakeBuildInfo to query the make rules.
STYLE: Allwmake script adjustments
- use bin/foamEtcFile instead of relying on PATH.
The make environment may not have the OpenFOAM bin/ in it.
- simpler shell syntax
Issues:
- neighbouring processors use different ray since always from
owner cc to nbr cc
- growing cellZones did not correctly unmark intersections
- stand-alone baffles now always removed (if inside 'grow' region,
i.e. within 1 cell of cellZone)
- the foamConfigurePaths script is quite simplistic and aggressive in
what it changes. This was particularly evident when using it to
change gcc/clang versions.
Restructured the corresponding compiler settings to define default
versions (eg, "default_gcc_version") that limits the scope of
changes performed by foamConfigurePaths and makes it easier to
understand if changing manually.

- provides an indirect access to a sub-section of a list that is
somewhat less efficient than a Foam::SubList, but supports the
following:
* adjustment of its addressing range after construction
* recovery of the original, underlying list at any time
This can be more convenient for some coding cases.
For example,
template<class Addr>
void renumberFaces(IndirectListBase<face, Addr>& faces, ...);
which can be called for
* Specific faces:
UIndirectList<face>(mesh.faces(), facesToChange)
* A sub-range of faces:
IndirectSubList<face>(mesh.faces(), pp.range())
* All faces:
IndirectSubList<face>(mesh.faces())
CONFIG: added IndirectListsFwd.H with some common forwarding
- the gcc c++/9 includes now inline strncpy, which obliterates
the previous method of suppressing the warning.
Now simply allocate additional space for the nul character.
COMP: silence some icc warnings
- make read construct from Istream explicit
BUG: sph(const SymmTensor2D<Cmpt>&)
- had incorrect constant, but the 2D routines still need more attention
(#1575)
- the vtkCellArray internal structure was still largely oriented on
the VTK legacy format, but has now been revised.
https://gitlab.kitware.com/vtk/vtk/merge_requests/5682
The `VTK_CELL_ARRAY_V2` define from vtkCellArray.h indicates
that the newer version is being used.
* In VTK-8.2.0 and older, sizes are interwoven (prefixed) in the
connectivity.
Connectivity: [n1, verts..., n2, verts... ]
When using these in vtkUnstructuredGrid, also needed a secondary
list of offsets for each of the starting locations.
* The update version now resembles a CompactListList. For example
Connectivity: [verts..., verts... ]
Offsets: [0, n1, n1+n2, n1+n2+n3... ]
The offsets are properly handled within vtkCellArray, and dropped as
an additional input for vtkUnstructuredGrid.
- indexing error in the output of values resulted in uniform output in
most cases.
- allocation error for on-the-fly triangulation
ENH: changed decomposed storage from DynamicList to plain faceList for
clearer allocation control and better overhead
- make stream constructors explicit
- remove "using std::ifstream", "using std::iofstream" statements
for a cleaner namespace.
* copy/move assignments for ITstream
* IStringStream: default construct and construct from std::string
instead of Foam::string
- reduce some overhead in masterOFstream
- simplify Pstream handling of string variants (#1525)
- this submodule (https://develop.openfoam.com/modules/visualization)
consolidates VTK-related visualization routines:
* catalyst
* paraview-plugins
* runTimePostProcessing
A benefit of this is make it easier to mix and match
different combinations of VTK/ParaView versions and capabilities
(Eg, MESA, MPI etc).
The catalyst submodule is now obsolete

- avoid stealing autoPtr in interpolationTable copy operations
- improve local memory requirements of readers
- make OpenFOAM table reader default constructible

(fix#1498 for csvTableReader as well)
Including `nu` in `DphitEff` even though it is not present in (LUU:Eq. 17)
provided higher level of resemblance to benchmarks for the tests considered,
particularly for the peak skin friction (yet, pressure-related predictions
were unaffected). Users can switch off `nu` in `DphitEff` by using
`includeNu` entry in `kEpsilonPhitFCoeffs` in order to follow the
reference paper thereat. `includeNu` is left `true` by default.

- remove (unused) Istream constructors, prune some unused methods,
rationalize write() vs writeDict().
Deprecate inconsistent construction order.
- handle empty names for ".ftr" surface patches (for plain triSurface
format) with double-quoted strings for more reliable streaming.
Written on a single line.
This is _backward_ compatible, but if users have been parsing these
files manually, they will need to adjust their code.
Previously:
```
(
frt-fairing:001%1
empty
windshield:002%2
empty
...
)
```
Updated (with example handling of empty name):
```
(
frt-fairing:001%1 empty
windshield:002%2 ""
...
)
```
- was in surfMesh/triSurface/patches/
now in OpenFOAM/meshes/Identifiers/surface/
This places the code closer to other identifier classes,
which aids in maintaining consistency
When more than one volumetric B-Splines control boxes are present, the
sensitivity constituents corresponding to the non-active design
variables were not bounded(zeroed) correctly. The resultant
sensitivities, used in the optimization, were bounded correctly, so this
was more a bug pertaining to the output file of the sensitivities rather
than a functional one.
- previously the store() method just set the ownedByRegistry flag.
Now ensure that it is indeed registered first.
- support register/store of tmp<> items.
The tmp parameter is not cleared, but changed from PTR to CREF
to allow further use.
The implicit registration allows code simplification using the
GeometricField::New factory method, for example.
Old Code
========
volScalarField* ptr = new volScalarField
(
IOobject
(

mesh.time().timeName(),
mesh,
IOobject::NO_READ,
IOobject::NO_WRITE,
true // Register
),
mesh,

ptr->store();
New Code
========
auto tptr = volScalarField::New
(

- kEpsilonPhitF is a kEpsilon-based model which originated
from (Durbin, 1995)’s v2-f methodology. However, the majority of
v2-f model variants proved to be numerically stiff for segregated
solution algorithms due to the coupled formulations of v2 and f fields,
particularly on wall boundaries.
The v2-f variant (i.e. OpenFOAM’s v2f model) due to
(Lien and Kalitzin, 2001) reformulated the original v2-f model to enable
segregated computations; however, a number of shortcomings regarding
the model fidelity were reported in the literature.
To overcome the shortcomings of the v2-f methodology, the v2-f approach
was re-evaluated by (Laurence et al., 2005) by transforming v2 scale into
its equivalent non-dimensional form, i.e. phit, to reduce the numerical
stiffness.
This variant, i.e. kEpsilonPhitF, is believed to provide numerical
robustness, and insensitivity to grid anomalies while retaining the
theoretical model fidelity of the original v2-f model.
Accordingly the v2f RANS model is deprecated in favour of the variant
kEpsilonPhitF model.
When activeDesignVariables are not set explicitly, all design variables
are treated as active. These were allocated properly when starting from
0 but not when starting from an intermediate optimisation cycle
(e.g. running 5 optimisation cycles, stopping and restarting).
TUT: added a new tutorial including the restart of an optimisation run
to help identify future regression
The controlBoxes wordList was removed from NURBS3DVolume in the
pre-release phase but writeMorpherCPs was not updated accordingly.
TUT: added the invocation of writeMorpherCPs in one of the tutotials to
help identify future regression
- The core of the FatalIOError message was not printed due to exiting
with FatalError instead of FatalIOError
- Changed the TypeName in all derived classes of displacementMethod so
that the toc printed by the FatalIOError corresponds to what the user
should add in dynamicMeshDict
When a contact resistance is used the T field on each coupled
patch is different due to the thermal resistance. Thus, instead
of solving for a unique Tw at the wall, we solve for Tw1 at one side
then, the Tnbr internal becomes Tw2, which is the T of the nbr
patch.

Many possibilities:
- use as a simple calculator with vectors, tensors etc.
- test validity of expression syntax
As a calculator:
foamCalc '(vector(1,2,3) ^ vector(4,5,6)) * sqrt(34)'
The same, but with debugging:
foamCalc -debug-switch fieldExpr=6 \
'mag((vector(1,2,3) ^ vector(4,5,6))) * sqrt(34)'
- previously just reported gcc/clang versions, but these are not
necessarily the ones actually being used (eg, clang-9 vs clang).
Now use the path from `wmake -show-path-cxx` to improve the accuracy,
and also support other compiler types.
1) New skewCorrectedSnGrad for non-orthogonal and skewness corrector
2) New freeSurfacePressure and freeSurfacePressure working with
interfaceTrackingFvMesh
3) New interfaceTrackingFvMesh
- now use debug 2 for scanner and debug 4 for parser.
Provided better feedback about what is being parsed (debug mode)
- relocate debug application to applications/tools/foamExprParserInfo

ENH: modify fWallFunction for kEpsilonPhitF model
The k-epsilon-phit-f turbulence closure model for incompressible and
compressible flows.
The model is a three-transport-equation linear-eddy-viscosity turbulence
closure model alongside an elliptic relaxation equation:
- Turbulent kinetic energy, \c k,
- Turbulent kinetic energy dissipation rate, \c epsilon,
- Normalised wall-normal fluctuating velocity scale, \c phit,
- Elliptic relaxation factor, \c f.

qem and qin were not set to zero for the wideBand model BC.
qin was used in the grey model BC to calculate Ir(the total
incoming heat flux). As it is now set to zero, the grey model
loops over the incoming rays to calculate Ir instead of relaying
on qin stored in radiativeIntensityRay.
- follows the principle of least surprise if the expansion behaviour

but escape for parcel the overall report will be wrong but
the local report for each patch is correct
- the PDRsetFields utility processes a set of geometrical obstructions
to determine the equivalent blockage effects.
These fields are necessary inputs for PDRFoam calculations.
After setting up the geometries, the -dry-run option can be used to
generate a VTK file for diagnosis and post-processing purposes.
- this is an initial release, with improvements slated for the future.
NOTE
- the field results may be less than fully reliable when run in
single-precision. This howver does not represent a realistic
restriction since the prepared fields target a combustion
application which will invariably be double-precision.
- locate where the user is less tempted to change it (#1515).
It really should be considered an invariant environment variable.
STYLE: wmake -help information to stdout, die errors to stderr
- The wmake -show-path-{c,cxx} options return the fully qualified
paths to the respective compilers. This can be useful when verifying
that the correct compiler is indeed configured.
- The -help-full to display the "advanced" options, but in the normal
case just show the basic options.
- reuse more of stringOps expansions to reduce code and improve the
syntax flexiblity.
We can now embed "pre-calculated" values into an expression.
For example,
angle 35;
valueExpr "vector(${{cos(degToRad($angle))}}, 2, 3)";
and the ${{..}} will be evaluated with the regular string evaluation
and used to build the entire expression for boundary condition
evaluation.
Could also use for fairly wild indirect referencing:
axis1 (1 0 0);
axis2 (0 1 0);
axis3 (0 0 1);
index 100;
expr "$[(vector) axis${{ ($index % 3) +1 }}] / ${{max(1,$index)}}";
- Failed due to double*Matrix<float> multiplication.
Style changes
- use SquareMatrix with Identity on construction
- use Zero in constructors
- remove trailing space and semi-colons
- skip processing OSspecific/MSwindows since this can cause duplicate
doxygen entries
STYLE: adjust formatting in code templates
STYLE: use std::string methods without extra qualifications
- ensure that the updateControl is "non-sticky" on re-read,
even if we do not support runtime-modifiable here
STYLE: add syntax example (wingMotion), but with updateInterval 1
- synchronize the scalar interval value with the integer version.
This ensures that the interval() method returns the correct
representative value.
- added clear() method to reset to 'always' (pass-through)
- ensure that the updateControl is "non-sticky" on re-read,
even if we do not support runtime-modifiable here
STYLE: add syntax example (wingMotion), but with updateInterval 1
The adjoint library is enhanced with new functionality enabling
automated shape optimisation loops. A parameterisation scheme based on
volumetric B-Splines is introduced, the control points of which act as
the design variables in the optimisation loop [1, 2]. The control
points of the volumetric B-Splines boxes can be defined in either
Cartesian or cylindrical coordinates.
The entire loop (solution of the flow and adjoint equations, computation
of sensitivity derivatives, update of the design variables and mesh) is
run within adjointOptimisationFoam. A number of methods to update the
design variables are implemented, including popular Quasi-Newton methods
like BFGS and methods capable of handling constraints like loop using
the SQP or constraint projection.

- when using VTK from ParaView sources it can better to tag them as
such, but simultaneously not mask the ParaView with hardware
rendering.
The additional ParaView_MESA_DIR variable allows this.
The balance of library and path setup is unaffected by this.
DOC: update doc/BuildIssues
- `Pkt` was directed to `GName` to allow wall functions
are usable by kkLOmega model
- `Pkt` was changed to a non-const object, so that omegaWallFunc
can modify `Pkt` at the wall, if need be.
- Elementwise backward compatibility was checked by
pimpleFoam/RAS/ellipsekkLOmega
- New implementation was checked by changing omega:hole boundary
in pimpleFoam/RAS/ellipsekkLOmega to omegaWallFunction
QRMatrix (i.e. QR decomposition, QR factorisation or orthogonal-triangular
decomposition) decomposes a scalar/complex matrix \c A into the following
matrix product:
\verbatim
A = Q*R,
\endverbatim
where
\c Q is a unitary similarity matrix,
\c R is an upper triangular matrix.
Usage
Input types:
- \c A can be a \c SquareMatrix<Type> or \c RectangularMatrix<Type>
Output types:
- \c Q is always of the type of the matrix \c A
- \c R is always of the type of the matrix \c A
Options for the output forms of \c QRMatrix (for an (m-by-n) input matrix
\c A with k = min(m, n)):
- outputTypes::FULL_R: computes only \c R (m-by-n)
- outputTypes::FULL_QR: computes both \c R and \c Q (m-by-m)
- outputTypes::REDUCED_R: computes only reduced \c R (k-by-n)
Options where to store \c R:
- storeMethods::IN_PLACE: replaces input matrix content with \c R
- storeMethods::OUT_OF_PLACE: creates new object of \c R
Options for the computation of column pivoting:
- colPivoting::FALSE: switches off column pivoting
- colPivoting::TRUE: switches on column pivoting
Direct solution of linear systems A x = b is possible by solve() alongside
the following limitations:
- \c A = a scalar square matrix
- output type = outputTypes::FULL_QR
- store method = storeMethods::IN_PLACE
Notes
- QR decomposition is not unique if \c R is not positive diagonal \c R.
- The option combination:
- outputTypes::REDUCED_R
- storeMethods::IN_PLACE
will not modify the rows of input matrix \c A after its nth row.
- Both FULL_R and REDUCED_R QR decompositions execute the same number of
operations. Yet REDUCED_R QR decomposition returns only the first n rows
of \c R if m > n for an input m-by-n matrix \c A.
- For m <= n, FULL_R and REDUCED_R will produce the same matrices
- handle zero or negative values as being identical to 1.
As per timeStep control and what the comments suggested.
- drop old outputTime enumeration, since this is covered by the
writeTime enumeration and a corresponding Enum name.
- support construction of a "pass-through" control object that always
executes and add some method to test for these conditions and be able
to output some meaning full information.
Eg,
if (ctrl.execute())
{
if (!ctrl.always())
{
Info<< "Sampling executed based on " << ctrl.type() << nl;
}
...
}
To produce "Sampling executed based on runTime"
Calculates the acoustic power due to the volume of isotropic turbulence
using Proudman's formula
The acoustic power \f$ P_A \f$ [W/m3] in terms of turbulence \f$ k \f$
and \f$ \epsilon \f$ is given as:
\f[
P_A = alpha_\epsilon \rho \epsilon M_t^5
\f]
where \f$ alpha_\epsilon \f$ is a constant (0.1) and
\f[
M_t = \frac{\sqrt{2 k}}{a_0}
\f]
with \f$ a_0 \f$ the speed of sound. The acoustic power is also output in
dB using:
\f[
L_P = 10 \log \frac{P_A}{P_ref}
\f]
where \f$ P_ref \f$ is a constant (1e-12 W/m3)
Usage
Example of function object specification to calculate the Proudman acoustic
power
proudmanAcousticPower1
{
type proudmanAcousticPower;
libs ("libfieldFunctionObjects.so");
...
// Required additional entries for incompressible calculations
rhoInf 1.225;
aRef 340;
}
Where the entries comprise:
Property | Description | Required | Default value
type | type name: proudmanAcousticPower | yes |
rhoInf | Freestream density for incompressible cases | no |
aRef | Reference spped of sound for incompressible cases | no |
alphaEps | Model coefficient | no | 0.1
Note
- The freestream density and reference speed of sound are only necessary
when a thermodynamics package is unavailable, typically for incompressible
cases.
- Allows user-defined control of when the mesh motion occurs,
which can be especially useful in situations where the mesh motion
is much slower than any of the fluid physics.
For example, in constant/dynamicMeshDict:
updateControl runTime;
updateInterval 0.5;
to have mesh motion triggered every 1/2 second.
Note that the _exact_ time that the mesh motion actually occurs may
be slightly differently since the "runTime" triggering is fuzzy in
nature. It will trigger when the threshold has been crossed, which
will depend on the current time-step size.
- The -Wno-deprecated-copy flag for gcc-9.2.0
In the future we may indeed wish to explicitly request default
generated constructors and assignment operators, but at the moment
these are still acceptable.
- The -Wno-alloc-size-larger-than flag for mingw compilations
Related to differences in PTRDIFF_MAX vs SIZE_MAX on the target.
Several issues related to this can be found in the gcc bug reports
and on stackoverflow etc.
COMP: delay evaluation of fieldToken enumeration types
- lazy evaluation at runTime instead of compile-time to make the code
independent of initialization order.
Otherwise triggers problems on gcc-4.8.5 on some systems where
glibc is the same age, or older.
Feature particle patch postpro filtering
### Summary
Adds options to write particle-patch interactions to file, and to select particle fields to post-process for the `patchPostProcessing` cloud function object
### Resolved bugs (If applicable)
none
### Details of new models (If applicable)
Cloud patch interaction models:
Optionally write patch interaction statistics, e.g. number and mass of particles that stick, escape etc. to file using the optional `writeToFile` entry, e.g.
```
localInteractionCoeffs
{
patches
(
"(walls|cyc.*)"
{
type rebound;
}
"inlet|outlet"
{
type escape;
}
);
// New optional entry
writeToFile yes;
}
```
Cloud function objects:
New `fields` optional entry can be used to select which particle fields to post-process; if empty or the entry is not given all fields are written (to provide backwards compatibility)
```
patchPostProcessing1
{
type patchPostProcessing;
// Optional new entry
fields (position "U.*" d T nParticle);
maxStoredParcels 20;
patches
(
cycLeft_half0
cycLeft_half1
);
}
```
See the `$FOAM_TUTORIALS/lagrangian/reactingParcelFilm/filter` tutorial for an example

Feature expressions
### Summary
This branch represents an implementation of what is considered to be the most useful aspects of swak4Foam ([Swiss-Army-Knife for FOAM](https://openfoamwiki.net/index.php/Contrib/swak4Foam)) from Bernhard Gschaider, namely the ability to use text-based expressions instead of coding in C++ for the following cases:
- expression-based boundary conditions (also known as _groovy_ boundary conditions)
- expression-based setFields (also known as _funky_ set fields)
The idea of what we currently term *expressions* was pioneered by
(Bernhard Gschaider) and is now firmly established in `swak4Foam`.
Among other things, expressions attempt to bridge the gap between
using standard, predefined boundary conditions and writing dedicated,
special-purpose ones. Although part of this gap is now covered within
OpenFOAM by using dynamically compiled user coding (eg, coded boundary
conditions), there remains substantial areas where it can be
significantly more convenient to have a series of predefined functions
and expression sytax with some access to base OpenFOAM field
functionality that enables rapid deployment of boundary conditions, or
custom-defined `setFields` without writing code.
A significant portion of `swak4Foam` expressions has been adapted for
direct integration into OpenFOAM. During the integration and rewrite,
we have tried to pare things down to a smaller subset with the aim of
covering 90% or more of the common cases. The remaining cases are left
to be reassessed for extending the *expressions* functionality in the
future, but they also may be better served with other approaches (eg,
with coded conditions) that were not available when `swak4Foam` was
originally conceived.
To the greatest extent possible, the integrated *expressions* have
been designed to avoid name clashes with `swak` so it should remain
possible to use the most recent versions of `swak` without problem.
### Risks
- New functionality, so low chance of regression.
- The scope of the functionality will be revised in the future
### Naming (for `swak4Foam` users)
The following are the *expressions* correspondences to `swak`:
- The `exprFixedValue` and `exprGradient` boundary conditions are
roughly equivalent to the _groovy_ boundary conditions.
- The utilities `setExprFields` and `setExprBoundaryFields` are
roughly equivalent to the _funky_ utilities of similar name.
The naming of the boundary conditions and utilities not only reflects
the slightly different input requirements, but simultaneously seeks to
avoid any potential name-clash with `swak4Foam` in a mixed
environment.
The names for the boundary condition dictionary entries tend be
shorter and slightly different (eg, `valueExpr` vs `valueExpression`)
to serve as a small reminder that the *expressions* syntax is slightly
different than the *groovy* equivalents. It also allows the user to
fashion dictionary entries that are sufficient for **both** boundary
condition variants and quickly toggle between them simply by changing
the boundary condition `type`.
See merge request Development/openfoam!300
Limits fields to user-specified min and max bounds
Usage
Example of function object specification:
limitFields1
{
type limitFields;
libs ("libfieldFunctionObjects.so");
...
fields (U);
limit max;
max 100;
}
Where the entries comprise:
Property | Description | Required | Default
type | type name: limitFields | yes |
fields | list of fields to process | yes |
limit | bound to limit - see below | yes |
min | min limit value | partly |
max | max limit value | partly |
The "limit" entry can take the value:
- min : specify a minimum value
- max : specify a maximum value
- both : specify a minimum value and a maximum value
The optional 'fields' entry can be used to limit which particle fields are
written to file. If empty/not specified, all properties are written to
maintain backwards compatibility.
patchPostProcessing1
{
type patchPostProcessing;
maxStoredParcels 20;
fields (position "U.*" d T nParticle);
patches
(
cycLeft_half0
cycLeft_half1
);
}
- replace stringOps::toScalar with a more generic stringOps::evaluate
method that handles scalars, vectors etc.
- improve #eval to handle various mathematical operations.
Previously only handled scalars. Now produce vectors, tensors etc
for the entries. These tokens are streamed directly into the entry.
This condition applies a scalar multiplier to the value of another
boundary condition.
Usage
Property | Description | Required | Default value
scale | Time varing scale | yes |
patch | patchField providing the raw patch value | yes |
Example of the boundary condition specification to scale a reference
velocity of (15 0 0) supplied as a fixedValue by a table of values
that ramps the scale from 0 to 1 over 1 second:
<patchName>
{
type scaledFixedValue;
scale table
(
( 0 0)
( 1.0 1.0)
(100.0 1.0)
);
patch
{
type fixedValue;
value uniform (15 0 0);
}
}
- The previous option 'write-nut' controlled the writing of turbulence
nut, but other turbulence fields were always written.
These have been shown to be a source of instability for many cases.
This commit replaces the 'write-nut' option by a 'writeTurbulenceFields'
option that controls the writing of all turbulence fields.
If not set, only the velocity field is written.
For compatibility, the old 'write-nut' option is still recognized
but is redirected to 'writeTurbulenceFields'.
Set the m4 -I include accordingly to have the folllowing:
- the directory of the parser.
- include/ in the top-level source tree of the current target
(eg, src/finiteVolume/include-m4/ when compiling libfiniteVolume)
- include/ from OpenFOAM
Additional -dry-run option for makeParser, wrap-lemon for expanding m4
only.
Extend m4 wrapping support to include bison as well.
- include the trailing newline for the "// comment" form, but also add
in leading space removal. This ensure that we do not introduce odd
indentation, while also eliminating lines that are solely C++
comments.
- output the "uniform", "nonuniform" Field entry tags as words instead
of raw character strings, which can help for direct tokenization or
when sending/receiving via Pstreams.
- some support for "uniform" bool fields. Calculating an averaged
value for a boolField does not work very well, but we simply define
that the field average is 'true' when more than 1/2 of its values
are true. Not exactly true, but allows templated definitions to work
smoothly.
- additional output method writeValue().
This outputs the single (uniform) value or the first value of the
field.
- ITstream append() would previously have used the append from the
underlying tokenList, which leaves the tokenIndex untouched and
renders the freshly appended tokens effectively invisible if
interspersed with primitiveEntry::read() that itself uses tokenIndex
when building the list.
The new append() method makes this hidden ITstream bi-directionality
easier to manage. For efficiency, we only append lists
(not individual tokens) and support a 'lazy' resizing that allows
the final resizing to occur later when all tokens have been appended.
- The new ITstream seek() method provides a conveniently means to move
to the end of the list or reposition to the middle.
Using rewind() and using seek(0) are identical.
ENH: added OTstream to output directly to a list of tokens
---
BUG: List::newElem resized incorrectly
- had a simple doubling of the List size without checking that this
would indeed be sufficient for the requested index.
Bug was not triggered since primitiveEntry was the only class using
this call, and it added the tokens sequentially.
This adds automatic deletion of cells inside small gaps. This is
generally used to avoid having excessive numbers of cells in irrelevant
areas of a geometry. It is nearly the opposite of automatic gap refinement
- that refines cells to resolve the gap; this functionality removes cells
to not mesh the gap.
The proximity handling will remove those cells which are inside 'thin' gaps
where 'thin' is defined as a distance of 2*'blockLevel'
It will
- detect surfaces which have the new 'blockLevel' specification
- convert this to a minimum gap distance
- detect cells which are inside this gap
- remove these cells and add exposed faces to the nearest 'real' patch
- allows use of Enum in more situations where a tiny Map/HashTable
replacement is desirable. The new methods can be combined with
null constructed for to have a simple low-weight caching system
for words/integers instead of fitting in a HashTable.
- since pointPatchField is not derived from Field, methods such as
negate() or a unary min(), max() are missing.
These have apparently not been needed thus far, but are used
indirectly via GeometricField.
- improves similarity to autoPtr. Simplifies coding.
Example,
tmp<volScalarField> tfield;
// sometime later...
tfield.reset
(
volScalarField::New("myfield", mesh, dimensionedScalar(Zero))
);
- as per tmp, disallow tmpNrc assignment from literal nullptr
- as per autoPtr, allow explicit test as bool (same as valid).
- can be useful when a scalarField has been used to store booleans and
we need to recover a bool directly and deal with potential rounding
issues.
ENH: support "any" as a Switch counterpart to "none"
- now indicate that the dictionary entry is missing, not that it is
an unknown function type.
STYLE: adjust PatchFunction1New.C to have logic structure look similar
- save in META-INFO/build-info for later re-compilation without git.
This improves tracking beyond simply referring to the the patch level.
The information is tagged with an underscore to distinguish from
"real" build information when git is available.
STYLE: improved shell syntax, pushd/popd guards etc.
- Previously, the default mapping method was `planarInterpolation` which was
silently suppressed by the default 'interpolate{R,U,L}=false'.
STYLE: changes:
`0` to `Zero`,
`lookupOrDefault` to `getOrDefault`
improves header documentation
- silently deprecate 'startsWith', 'endsWith' methods
(added in 2016: 2b14360662), in favour of
'starts_with', 'ends_with' methods, corresponding to C++20 and
allowing us to cull then in a few years.
- handle single character versions of starts_with, ends_with.
- add single character version of removeEnd and silently deprecate
removeTrailing which did the same thing.
- drop the const versions of removeRepeated, removeTrailing.
Unused and with potential confusion.
STYLE: use shrink_to_fit(), erase()
Example - create p-rgh from p:
pressure-p-rgh
{
type pressure;
libs (fieldFunctionObjects);
writeControl writeTime;
mode static;
rho rhoInf;
rhoInf 1;
hydrostaticMode subtract;
g (0 -9.81 0);
hRef 0;
}
- the hydrostaticMode entry is optional - setting is shown during construction
- g and/or hRef values are retrieved from the database if not specified
- This scheme is useful to calculate the face interpolation values for
the Gauss gradient when the diffussion coefficient is discontinuous
across a face. This sheme is used for Gauss grad.
- use sed instead of foamDictionary and avoid log file
- ensure consistent behaviour with plot script
GIT: added missing 0/k field : inlet values still need adjustment
- can be helpful, for example, when the refCast has been used on a
boundary patch. Knowing which patch index triggered the problem
helps with isolating the issue.
For example,
$ someSolver -info-switch writeOptionalEntries
- note that values changed via the command-line are changed after the
etc/controlDict entries, but *before* any case-local
system/controlDict entries.
However, in many testing cases the command-line options eliminate
the need for such local file modifications.
ENH: cleanup handling of local debug switches in Time
- add as methods directly on simpleObjectRegistry to avoid code
duplication
STYLE: adjust internal naming of ITstream parameters
- now reports the dictionary, entry, default. For example,
Dictionary: <case>/0/nut.boundaryField.wall Entry: Cmu Default: 0.09
Dictionary: <case>/0/nut.boundaryField.wall Entry: kappa Default: 0.41
Dictionary: <case>/0/nut.boundaryField.wall Entry: E Default: 9.8
- suppress reporting for debug, optimisation switches since this
generates extremely noisy output
- Now accept '/' when reading variables without requiring
a surrounding '{}'
- fix some degenerate parsing cases when the first character is
already bad.
Eg, $"abc" would have previously parsed as a <$"> variable, even
although a double quote is not a valid variable character.
Now emits a warning and parses as a '$' token and a string token.
- add toScalar evaluation, embedded as "${{EXPR}}".
For example,
"repeat ${{5 * 7}} times or ${{ pow(3, 10) }}"
- use direct string concatenation if primitive entry is only a string
type. This prevents spurious quotes from appearing in the expansion.
radius "(2+4)";
angle "3*15";
#eval "$radius*sin(degToRad($angle))";
We want to have
'(2+4)*sin(degToRad(3*15))'
and not
'"(2+4)"*sin(degToRad("3*15"))'
ENH: code refactoring
- refactored expansion code with low-level service routines now
belonging to file-scope. All expansion routines use a common
multi-parameter backend to handle with/without dictionary etc.
This removes a large amount of code duplication.
- add floor/ceil/round methods
- support evaluation of sub-strings
STYLE: add blockMeshDict1.calc, blockMeshDict1.eval test dictionaries
- useful for testing and simple demonstration of equivalence
- SubField and SubList assign from zero
- SubField +=, -=, *=, /= operators
- SubList construct from UList (as per SubField)
Note: constructing an anonymous SubField or SubList with a single
parameter should use '{} instead of '()' to avoid compiler
ambiguities.
- drop plugin support for Qt4 (old paraview)
- handle upcoming changes in VTK version naming in CMake files
* VTK_MAJOR_VERSION becomes VTK_VERSION_MAJOR etc.
- Improves header file documentations
- Adds const specifier to various objects
- Allows various model constants to be user-defined
- Changes from lookupOrDefault() to getOrDefault()
- Consistent namespace usage:
- If the WF belongs to only Foam:: namespace, use Foam:: explicitly
- If the WF belongs to more than one namespaces, put the WF in namespace
parentheses
- Adds the missing dashes in comments required by Doxygen
- Corrects capitalisation in comments
- The terminology 'viscous sublayer' was preferred over 'laminar sublayer'
due to the fact that the sublayer is not laminar.
- The order of initialisation of fields is changed to be the same across all.
OpenFOAM.org commits for
src/TurbulenceModels/turbulenceModels/derivedFvPatchFields/wallFunctions
were reviewed.
The parts of the commits made by OpenFOAM.org removing various code
duplications across wall functions were picked up by keeping the remaining
functionalities the same.
The duplications were mainly due to:
- wall function model coefficients
- yPlusLam(), checkPatch(), write() methods
The duplications were united under the base nutWallFunction.
- since a zero-sized FixedList is disallowed, the accessors to the
first/last elements are always known.
This allows Pair second() to be noexcept as well (as per Tuple2)
- the #eval directive is similar to the #calc directive, but for evaluating
string expressions into scalar values. It uses an internal parser for
the evaluation instead of dynamic code compilation. This can make it
more suitable for 'quick' evaluations.
The evaluation supports the following:
- operations: - + * /
- functions: exp, log, log10, pow, sqrt, cbrt, sqr, mag, magSqr
- trigonometric: sin, cos, tan, asin, acos, atan, atan2, hypot
- hyperbolic: sinh, cosh, tanh
- conversions: degToRad, radToDeg
- constants: pi()
- misc: rand(), rand(seed)
- previously allowed mapped value modification with a const iterator.
However, this can lead to incorrect access patterns.
Now tie the constness of the mapped value to that of the iterator.
- Remove deprecated iterator object() method.
Was only used internally and was superseded by the val() method
in an earlier version.
ENH: change isPointer to isPointerLike
- can distinguish between real pointers and wrapped pointers
- this largely reverts 3f0f218d88 and 4ee65d12c4.
Consistent addressing with support for wrapped pointer types (eg,
autoPtr, std::unique_ptr) has proven to be less robust than desired.
Thus rescind HashTable iterator '->' dereferencing (from APR-2019).
- for special cases when normal writing is to be completely disabled
and replaced with alternate means (eg, via a function object).
- support "adjustable" as "adjustableRunTime" alias to reduce typing
for writeControl or outputControl
- use HashTable emplace instead of insert to avoid unneeded argument
(for HashSet).
- use emplace when generating zero-initialized values for
HashTable::operator()
- drop unused parameter from Detail::HashTableSingle,
adjust templates parameter names
- forward HashTable::operator[] to the semantically identical
HashTable::at() to avoid code duplication
- call also be used non-interactively for simple 'one-shot' use of
OpenFOAM utilities or solvers
STYLE: use dash instead of brackets for '- see www.OpenFOAM.com'
- less cluttered in combination with API information
- now maintains a correct list of geometry instances, without assuming
contiguous file numbering. However, if the numbering is contiguous,
the more compact case representation will be used.
- an advanced feature, for example when sampling on a static patch
while some motion occurs elsewhere. [use with caution]
- If the sampled surface dictionary is modified during run-time, the
ensight file indexing for the geometry will become out of sync.
This is addressed in a subsequent commit.
- this can be useful for preloading of libraries, or for utilities
that don't use system/controlDict.
The additional libraries can be specified individually:
myUtil -lib lib1 -lib lib2 -lib lib3
When specified like this, the options add up.
Or as a 'captured' list using OpenFOAM's standard arg list handling:
myUtil -lib '(' lib1 lib2 lib3 ')'
myUtil -lib \( lib1 lib2 lib3 \)
or as single argument list:
myUtil -lib '("lib1" "lib2" "lib3")'
When specified as a single argument, would normally take advantage
of the transparent handling of word vs fileName and omit the string
quotes:
myUtil -lib '(lib1 lib2 lib3)'
ENH: dlOpen error messages now propagated into dlLibraryTable
- this makes the context more relevant and also avoids the previous
annoyance of double warnings (one from the POSIX loader, and one
from dlLibraryTable)
STYLE: mark -noFunctionObjects and -withFunctionObjects as 'advanced'
- reduces clutter. Still visible with -help-full
- add additional rule (ending '.ll') for the combination of
flex for C-code but compiling the result as C++.
This can be needed for re-entrant parsers.
- update bison rule to handle renaming of skeleton files.
Use a wrap-bison script to manage this.
- relax casting rules
* down-cast of labelToken to boolToken
* up-cast of wordToken to stringToken.
Can use isStringType() test for word or string types
- simplify constructors, move construct etc.
- expose reset() method as public, which resets to UNDEFINED and
clears allocated storage etc.
DEFEATURE: remove assign from word or string pointer.
- This was deprecated 2017-11 and now removed.
For this type of content transfer, move assignment should be used
instead of stealing pointers.
1) Add softWall rigidBody restrain
2) Add linearSpringDamper sixDoF restrain to work as soft rope
3) dynamicMotionSolverListFvMesh changed to dictionary based input
4) Add Time reference access to sixDof restraints
5) Add drivenLinearMotion to solidBodyMotionFunctions.
- allows some internal handling for reading dissimilar storage types.
Eg, scalars written as float (WM_SP), but read as double (WM_DP)
- reading binary parcel coordinates with dissimilar storage types is
still pending
- change contiguous from a series of global functions to separate
templated traits classes:
- is_contiguous
- is_contiguous_label
- is_contiguous_scalar
The static constexpr 'value' and a constexpr conversion operator
allow use in template expressions. The change also makes it much
easier to define general traits and to inherit from them.
The is_contiguous_label and is_contiguous_scalar are special traits
for handling data of homogeneous components of the respective types.
- in addition to m() and n(), provide Matrix mRows()/nRows(), nCols()
methods. These provide unambiguous access names.
'mRows()' == for internal consistency with MatrixSpace.
'nRows()' == a commonly used naming.
- with 1906, OpenFOAM is purely C++ code and the last toolchain bits C
code have been avoided. Thus relax the wmake C rule for including
WM_COMPILE_OPTION. This makes it much easier to add different
compiler options with fewer files.
For example, for Broadwell-specific options:
cd wmake/rules/linux64Gcc
cp c++Opt c++OptBdw
edit this file and then use WM_COMPILE_OPTION=OptBdw
- ensure that WM_COMPILE_OPTION is always non-empty
- a top-level cloud::nParcels() virtual, which is overloaded by the
first level of Cloud inheritance. This permits quick determination of
cloud sizes, even when retrieved from registry with the base level.
Eg,
cloud* cldPtr = mesh.cfindObject<cloud>("myCloud");
label nParcels = (cldPtr ? cldPtr->nParcels() : 0);
- make writeLagrangianPositions on by default unless explicitly
disabled in the InfoSwitches.
Flag output errors (where neither coordinates nor positions are
written) with Fatal.
- additional IOField helper functions in cloud
STYLE: simplify iterator inheritance
- can now specify literal matches for sub-dictionary methods:
isDict(key, keyType::REGEX)
optionalSubDict(key, keyType::REGEX)
subDict(key, keyType::REGEX)
subOrEmptyDict(key, keyType::REGEX, mandatory)
There is no change in behaviour of the methods, just the search option
is now exposed as an optional parameter.
NOTE: minor breaking change for subOrEmptyDict()
old: subOrEmptyDict(key, bool=false)
new: subOrEmptyDict(key, keyType::option=keyType::REGEX, bool=false)
This affects code that previously explicitly set the bool parameter.
Within OpenFOAM itself, this only affected a single file:
KinematicCloud.C
- this is principally for cases where reduced indentation is desired,
such as when streaming to a memory location. If the indentation size
is zero or one, only a single space will be used to separate the
key/value.
This change does not affect the stream allocation size, since the
extra data falls within the padding.
ENH: relocate label/scalar sizes from Istream to IOstream.
- could allow future use for output streams as well?
Due to padding, reorganization has no effect on allocated size
of output streams.
STYLE: add read/write name qualifier to beginRaw, endRaw
- removes ambiguity for bi-directional streams
STYLE: fix inconsistent 'const' qualifier on std::streamsize
- base Ostream was without const, some derived streams with const
- allows full recovery of allocated space, not just addressable range.
This can be particularly useful for code patterns that repeatedly
reuse the same buffer space. For example,
DynamicList<char> buf(1024);
// some loop
{
OListStream os(std::move(buf));
os << ...
os.swap(buf);
}
Can read back from this buffer as a second operation:
{
UIListStream is(buf);
is >> ...
}
- When building OpenFOAM for different platform combinations
(single/double, int32/int64) the build information that is compiled
into the OpenFOAM lib can become out of sync.
This is because the update trigger (wmakeBuildInfo -check) is
independent of the targetted platform. The added file
'src/OpenFOAM/Alltouch' provides a direct means of forcing a rebuild
of the version information. Eg,
src/OpenFOAM/Alltouch
wmake src/OpenFOAM
Also provide an additional 'wmakeBuildInfo -remove' to forcibly
remove META-INFO/build-info, if that is desired.
- symmetric with writeRaw() etc for the output stream. These are
methods that are not required by normal users, but which provide
a finer granularity for reading.
- additional information about the current stream position when
endList fails. This may help when tracing errors.
STYLE: change return type of beginRaw()/endRaw() to bool
- was of type Ostream& for output, but return value was unused.
Having bool may be better for encapsulating logic
STYLE: remove unused Istream::readEndBegin() function
- in InterfaceCompositionPhaseChangePhaseSystem, the mass transfer
rates are updated as a side-effect of the massTransfer() method,
which makes these fields non-const.
- adapted openfoam.org code. Original commit message:
Instead of adapting tet base points cell-by-cell, the dangling
points are pre-computed and then the adaptations to the base points
are made face-by-face. This correctly adapts faces which have
different dangling points relative to the owner and neighbour cells.
- treat the faces that would be exposed on a subset as boundary faces
for the erosion algorithm
STYLE: adjust code for consistency between isoSurfaceCell and isoSurfaceTopo
- add an 'isoAlgorithm' keyword to distance surface and cutting plane
to advance further testing of the isoSurfaceTopo algorithm.
Does not yet handle the full spectrum of bound boxes, cellZones etc.
- unfriend HashSet, HashTable IO operators
- global min(), max(), minMax() functions taking a labelHashSet and an
optional limit. For example,
labelHashSet set = ...;
Info<< "min is " << min(set) << nl;
Info<< "max (non-negative) " << max(set, 0) << nl;
- make HashTable iterator '->' dereferencing more consistent by also
supporting non-pointer types as well.
- read HashTable values in-situ to avoid copying
- the Enum::readEntry() method was previously as bit sloppy with
respect to the enumeration that it accepted. If the input was
non-mandatory, typos would go unnoticed. Now tighten things so that
if an enumeration is found, it must also be valid.
STYLE: remove unused/deprecated Enum::lookupOrFailsafe() method
- this was only used in a few places internally in 1712 and 1806 but
has since then been superseded by getOrDefault() with an optional
'failsafe' flag.
- An identity is often useful when generating connectivity and offset
information.
- The optional repeat value for vtk::write() allows it to also be used
as a fill method.
Modifications to help avoid inadvertent overwriting of tutorialsTest:
- new '-force' option to overwrite existing directory
- generate a 'tutorialsTest/Alltest' script that disallows the
possibilty of self-recursion
- reverse mapping for the original point ids. This can be useful
when searching a subset of points, but needing to store access to
the original point index.
- move constructor.
- Allow use/not-use subset as an optional constructor argument for
more convenient caller logic.
- changed for 1906 to have a regIOobject always cleanup its
objectRegistry entry. No need to explicitly 'release' ownership
for this to now happen.
- doxygen formatting for MeshObject
