- Extended runTimePostProcessing to include access to "live"
simulation objects such a geometry patches and sampled surfaces
stored on the "functionObjectObjects" registry.
- Add 'live' runTimePostProcessing of cloud data.
Extracts position and fields from the cloud via its objectRegistry writer
- For the "live" simulation objects, there are two new volume filters
that work directly with the OpenFOAM volume fields:
* iso-surface
* cutting planes
Both use the VTK algorithms directly and support multiple values.
Eg, can make multiple iso-levels or multiple planes parallel to each
other.
- When VTK has been compiled with MPI-support, parallel rendering will
be used.
- Additional title text properties (shadow, italic etc)
- Simplified handling of scalar-bar and visibility switches
- Support multiple text positions. Eg, for adding watermark text.
- the utility had automatic triangulation removed some time ago, but
never changed its name.
- catch old uses with a surfaceMeshTriangulate deprecated script
- makes the intent clearer and avoids the need for additional
constructor casting. Eg,
labelList(10, Zero) vs. labelList(10, 0)
scalarField(10, Zero) vs. scalarField(10, scalar(0))
vectorField(10, Zero) vs. vectorField(10, vector::zero)
- this corresponds to 'never match', which may be useful in combination
with -constant selection.
Eg,
surfaceMeshTriangulate -constant -time none
selects only the constant entry and suppresses any automatic time loop
STYLE: adjust help for the standard -times option
- indicate that times can be comma or space separated, since this is
otherwise not apparent. Don't mention semicolon separators in the help
since that just adds even more clutter.
- support .vtp format for geometry, surface, line, cloud.
- use native reader for handling vtk, vtp, obj, stl surface files.
For other formats, use the MeshedSurface (the surfMesh lib) to
handle reading and Foam::vtk::Tools::Patch to handle the
conversion to vtkPolyData. This combination is more memory efficient.
- update tutorial case to include vtp surface geometry
- this allows more use of the runTimePostProcessing functionObject
that will fail more gracefully if the proper version could not be
built.
The dummy functionObject simply emits a message that it is not available.
Reports the min|max|average AMI weights to text file and optionally
writes VTK surfaces of the sum of the weights, and mask field for
ACMI patches.
Example usage:
AMIWeights
{
type AMIWeights;
libs ("libfieldFunctionObjects.so");
writeControl writeTime;
writeFields yes;
}

- deprecate dimensionedType constructors using an Istream in favour of
versions accepting a keyword and a dictionary.
Dictionary entries are almost the exclusive means of read
constructing a dimensionedType. By construct from the dictionary
entry instead of doing a lookup() first, we can detect possible
input errors such as too many tokens as a result of a input syntax
error.
Constructing a dimensionedType from a dictionary entry now has
two forms.
1. dimensionedType(key, dims, dict);
This is the constructor that will normally be used.
It accepts entries with optional leading names and/or
dimensions. If the entry contains dimensions, they are
verified against the expected dimensions and an IOError is
raised if they do not correspond. On conclusion, checks the
token stream for any trailing rubbish.
2. dimensionedType(key, dict);
This constructor is used less frequently.
Similar to the previous description, except that it is initially
dimensionless. If entry contains dimensions, they are used
without further verification. The constructor also includes a
token stream check.
This constructor is useful when the dimensions are entirely
defined from the dictionary input, but also when handling
transition code where the input dimensions are not obvious from
the source.
This constructor can also be handy when obtaining values from
a dictionary without needing to worry about the input dimensions.
For example,
Info<< "rho: " << dimensionedScalar("rho", dict).value() << nl;
This will accept a large range of inputs without hassle.
ENH: consistent handling of dimensionedType for inputs (#1083)
BUG: incorrect Omega dimensions (fixes#2084)
- helps reduce clutter in the topoSetDict files.
Caveats when using this.
The older specification styles using "name" will conflict with the
set name. Eg,
{
name f0
type faceSet;
action add;
source patchToFace;
sourceInfo
{
name inlet;
}
}
would flattened to the following
{
name f0
type faceSet;
action add;
source patchToFace;
name inlet;
}
which overwrites the "name" used for the faceSet.
The solution is to use the updated syntax:
{
name f0
type faceSet;
action add;
source patchToFace;
patch inlet;
}
- old 'DELETE' enum was easily confused with 'REMOVE', which removes
the set, not the elements from the set.
- provide corresponding subtractSet() method
STYLE: HashSet set/unset instead of insert/erase methods in topoSetSource
- simplifies switching to/from bitSet storage
- signedDistance() method is like distance() but retains
the positive/negative sign for the side of the plane.
- the sign() method returns the sign as -1,0,+1 integer for
classification purposes where it is important to distinguish between
a zero value and a positive value (eg, for cutting). Optional
tolerance can be supplied to round for zero.
- refactor and inlined simple and frequently used methods.
- add boundBox faceCentre() method, which can be useful for creating
clipping planes from a bounding box.
Relocated treeBoundBox faceNormals to boundBox since they apply
equally there - the meaning of the faces (x-min, x-max, etc)
is the same, even if the point addressing for the faces differs.
- improve doxygen entries for searchable surfaces.
- support selection of searchable surfaces with shorter names.
Eg,
type box | cylinder | ...;
vs type searchableBox | searchableCylinder | ...;
- relocate some standard functionality to TimePaths to allow a lighter
means of managing time directories without using the entire Time
mechanism.
- optional enableLibs for Time construction (default is on)
and a corresponding argList::noLibs() and "-no-libs" option
STYLE:
- mark Time::outputTime() as deprecated MAY-2016
- use pre-increment for runTime, although there is no difference in
behaviour or performance.
Now pimpleDyMFoam is exactly equivalent to pimpleFoam when running on a
staticFvMesh. Also when the constant/dynamicMeshDict is not present a
staticFvMesh is automatically constructed so that the pimpleDyMFoam solver can
run any pimpleFoam case without change.
pimpleDyMFoam: Store Uf as an autoPtr for better error handling
pimpleFoam: Set initial deltaT from the Courant number
for improved stability on start-up and compatibility with pimpleDyMFoam
ENH: pimpleFoam: Merged dynamic mesh functionality of pimpleDyMFoam into pimpleFoam
and replaced pimpleDyMFoam with a script which reports this change.
The pimpleDyMFoam tutorials have been moved into the pimpleFoam directory.
This change is the first of a set of developments to merge dynamic mesh
functionality into the standard solvers to improve consistency, usability,
flexibility and maintainability of these solvers.

tutorials/incompressible/pimpleFoam: Updated pimpleDyMFoam tutorials to run pimpleFoam
Renamed tutorials/incompressible/pimpleFoam/RAS/wingMotion/wingMotion2D_pimpleDyMFoam

- controlled by the the 'printExecutionFormat' InfoSwitch in
etc/controlDict
// Style for "ExecutionTime = " output
// - 0 = seconds (with trailing 's')
// - 1 = day-hh:mm:ss
ExecutionTime = 112135.2 s ClockTime = 113017 s
ExecutionTime = 1-07:08:55.20 ClockTime = 1-07:23:37
- Callable via the new Time::printExecutionTime() method,
which also helps to reduce clutter in the applications.
Eg,
runTime.printExecutionTime(Info);
vs
Info<< "ExecutionTime = " << runTime.elapsedCpuTime() << " s"
<< " ClockTime = " << runTime.elapsedClockTime() << " s"
<< nl << endl;
--
ENH: return elapsedClockTime() and clockTimeIncrement as double
- previously returned as time_t, which is less portable.
