NAME
freefoam-splitMeshRegions - Splits mesh into multiple regions.
SYNOPSIS
freefoam splitMeshRegions [-cellZones] [-help] [-makeCellZones] [-sloppyCellZones] [-blockedFaces <faceSet name>] [-largestOnly] [-srcDoc] [-doc] [-overwrite] [-insidePoint <point>] [-parallel] [-case <dir>] [-detectOnly]
DESCRIPTION
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)
OPTIONS
- -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.
NOTE
• 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
