freefoam-splitMeshRegions - Splits mesh into multiple regions.
freefoam splitMeshRegions [-cellZones] [-help] [-makeCellZones] [-sloppyCellZones] [-blockedFaces <faceSet name>] [-largestOnly] [-srcDoc] [-doc] [-overwrite] [-insidePoint <point>] [-parallel] [-case <dir>] [-detectOnly]
Each region is defined as a domain whose cells can all be reached by cell-face-cell walking without crossing - boundary faces - additional faces from faceset (-blockedFaces faceSet). - any face inbetween differing cellZones (-cellZones) Output is: - volScalarField with regions as different scalars (-detectOnly) or - mesh with multiple regions or - mesh with cells put into cellZones (-makeCellZones)
-cellZones Split different cell zones. -detectOnly Do no processing. -blockedFaces <faceSet name> Split at give face set. -sloppyCellZones Try to match regions to existing cell zones. -makeCellZones Create mesh with cells in different cell zones. -overwrite Overwrite existing data. -case <dir> Case directory. -parallel Run in parallel. -help Display help message. -doc Display Doxygen API documentation page for this application. -srcDoc Display Doxygen source documentation page for this application. -insidePoint <point> Only keep region containing specified point. -largestOnly Only keep largest region.
· cellZonesOnly does not do a walk and uses the cellZones only. Use this if you don’t mind having disconnected domains in a single region. This option requires all cells to be in one (and one only) cellZone. · cellZonesFileOnly behaves like -cellZonesOnly but reads the cellZones from the specified file. This allows one to explicitly specify the region distribution and still have multiple cellZones per region. · useCellZonesOnly does not do a walk and uses the cellZones only. Use this if you don’t mind having disconnected domains in a single region. This option requires all cells to be in one (and one only) cellZone. · Should work in parallel. cellZones can differ on either side of processor boundaries in which case the faces get moved from processor patch to directMapped patch. Not very well tested. · If a cell zone gets split into more than one region it can detect the largest matching region (-sloppyCellZones). This will accept any region that covers more than 50% of the zone. It has to be a subset so cannot have any cells in any other zone. · writes maps like decomposePar back to original mesh: · pointRegionAddressing : for every point in this region the point in the original mesh · cellRegionAddressing : ,, cell ,, cell ,, · faceRegionAddressing : ,, face ,, face in the original mesh + turning index. For a face in the same orientation this is the original facelabel+1, for a turned face this is -facelabel-1
