- before (-lreactingPhaseSystem -ltwoPhaseReactingTurbulenceModels)
after (-ltwoPhaseReactingTurbulenceModels -lreactingPhaseSystem)
to fix symbol resolution issue on clang.
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.
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
- `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
- 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.
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.
- 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.

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
- 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
