Now both the checkMesh utility and functionObject operate in the same manner
with the same controls, executing the same checkGeometry and checkTopology
functions from the new meshCheck library. The controls have been updated and
made more consistent and flexible, in particular by the addition of optional
user specification for the non-orthogonality and skewness error thresholds:
Application
checkMesh
Description
Checks validity of a mesh.
Usage
\b checkMesh [OPTION]
Options:
- \par noTopology
Skip checking the mesh topology
- \par -allTopology
Check all (including non finite-volume specific) addressing
- \par -allGeometry
Check all (including non finite-volume specific) geometry
- \par -meshQuality
Check against user defined (in \a system/meshQualityDict) quality
settings
- \par -region \<name\>
Specify an alternative mesh region.
- \par -writeSurfaces
Reconstruct cellSets and faceSets of problem faces and write to
postProcessing directory.
- \par -surfaceFormat <format>
Format used to write the cellSets and faceSets surfaces
e.g. vtk or ensight.
- \par -writeSets
Reconstruct pointSets of problem points nd write to
postProcessing directory.
- \par -setFormat <format>
Format used to write the pointSets
e.g. vtk or ensight.
- \par -nonOrthThreshold <threshold value in degrees>
Threshold in degrees for reporting non-orthogonality errors,
default: 70"
- \par -skewThreshold <threshold value>
Threshold for reporting skewness errors, default: 4.
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

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;
}
\endverbatim
or using the standard configuration file:
\verbatim
#includeFunc checkMesh(executeInterval=10, allGeometry=true)
\endverbatim
