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
