This prevents spurious factors of 1000 from being introduced in
thermodynamic models. It also generalises the system further with
respect to alternative unit sets.
The legacy fvMeshTopoChangersMovingCone removed, replaced by the more general
mesh mapping approach, see tutorials incompressibleFluid/movingCone and
shockFluid/movingCone.
This returns the fraction of the poly-face that each fv-face in the
patch covers. This is useful for mapping some calculations from the
polyMesh to the fvMesh in cases with non-conformal couplings.
The 'U0' entry in the patch injection model can now specify a field name
from which the initial velocity will be interpolated. It can also, as
before, specify a fixed velocity vector.
The specie molecular mass (Wi) and formation enthalpy (hfi) methods now
return dimensioned scalars. This permits their direct inclusion into
dimensioned field expressions. Non-dimensioned methods have been
retained with a "Value" suffix (i.e., WiValue and hfiValue).
This function now looks up an alphaPhi field by default and exits with
an error if the field cannot be found. In order to solve for alphaPhi a
new 'solveAlphaPhi' switch has to be set.
The documentation has been updated to reflect the fact that the VoF
solvers now store all the alphaPhi fluxes necessary for a in-phase
equation to be constructed.
The phaseScalarTransport function has been added to the damBreakLaminar
tutorial.
All property functions in the low-level templated thermo property
implementations and the high-level virtual interfaces have been made
consistent. All energies and enthalpies are lower case to denote that
they are specific quantities. Molar functions have been removed as these
are no longer used anywhere.
The nearWallDist MeshObject is now deleted on mesh-change rather than updated
which is more efficient for cases with multiple mesh changes, e.g. motion,
stitching and mapping by avoiding unnecessary updates.
As a consequence of this change the wallDist::y() volScalarField reference
should not be cached across mesh changes so the turbulence models now obtain the
y field as required from the new momentumTransportModel::y() function, the
original near-wall distance function is now named momentumTransportModel::yb()
to clarify that it is the wall distance of the boundary cells.
The nearWallDist MeshObject is now deleted on mesh-change rather than updated
which is more efficient for cases with multiple mesh changes, e.g. motion,
stitching and mapping by avoiding unnecessary updates.
It is simpler and more consistent to declare topological mesh objects as
moveable with a dummy movePoints function so that they remain unchanged if the
mesh moves without topology change. This allows the TopologicalMeshObject to be
removed altogether, the base MeshObjects type now being DeletableMeshObject
which are deleted on mesh change.
volPointInterpolation is now deleted on mesh-change rather than updated which is
more efficient for cases with multiple mesh changes, e.g. motion, stitching and
mapping by avoiding unnecessary updates.
Description
Executes primitiveMesh::checkMesh(true) every execute time for which the
mesh changed, i.e. moved or changed topology.
Useful to check the correctness of changing and morphing meshes.
Usage
\table
Property | Description | Required | Default value
type | type name: checkMesh | yes |
noTopology | Skip checking the mesh topology | no | false
allTopology | Check all addressing | no | false
allGeometry | Check all geometry | no | false
writeSurfaces | Reconstruct and write problem faces | no | false
surfaceFormat | Format for problem faceSets | no | vtk
writeSets | Reconstruct and write problem points | no | false
setFormat | Format used to write the problem pointSets | no | vtk
nonOrthThreshold | Threshold for non-orthogonality errors | no | 70 deg
skewThreshold | Threshold for reporting skewness errors | no | 4
stopAt | Stops the run if any mesh checks fail | no | endTime
\endtable
The optional \c stopAt option may be set to
- endTime : Continue running on error
- noWriteNow : Stops the run on error without write
- writeNow : Stops the run on error and writes fields
- nextWrite : Stops the run at the next write time on error
Example of checkMesh specification:
\verbatim
checkMesh
{
type checkMesh;
libs ("libutilityFunctionObjects.so");
executeControl timeStep;
executeInterval 10;
allGeometry true;
allTopology true;
writeSurfaces true;
surfaceFormat vtk;
writeSets true;
setFormat vtk;
stopAt writeNow;
}
\endverbatim
or using the standard configuration file:
\verbatim
#includeFunc checkMesh(executeInterval=10, allGeometry=true)
\endverbatim
This is consistent with the fluid solvers, and prevents failures
associated with using fields that haven't yet been updated or corrected
following mesh changes
This simple model creates a heat transfer coefficient in proportion with
the corresponding drag model's momentum transfer coefficient. A
user-defined Prandtl number and a harmonic average of the phases'
specific heats are used to specify the constant of proportionality.
This model has no physical basis. It exists primarily for testing
purposes. It has the advantage of being applicable to any interface,
including those representing segregated configurations.
Example usage:
heatTransfer
{
gas_segregatedWith_liquid
{
type Prandtl;
Pr 0.7;
}
}
These classes permit any PtrList of region-associated objects (meshes,
solvers, domainDecompositions, ...) to prefix the region name to the log.
At present these classes are used by decomposePar and reconstructPar
only. The foamMultiRun solver still handles its own prefixing.
The final iteration state is now available from the solutionControl class via
the new finalIteration() static function, replacing the old data class from
which fvMesh was derived. This approach is simpler, more reliable and easier to
extend and reduces the clutter associated with fvMesh.
