Class
Foam::functionObjects::checkMesh
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
