       Split mesh into multiple regions (detected by walking across faces)

       splitMeshRegions - part of OpenFOAM (The Open Source CFD Toolbox).

-blockedFacesfaceSet
              Specify additional region boundaries that walking does not cross

       -casedir
              Specify case directory to use (instead of the cwd)

       -cellZones
              Additionally split cellZones off into separate regions

       -cellZonesFileOnlyfile
              Like -cellZonesOnly, but use specified file

       -cellZonesOnly
              Use cellZones only to split mesh into regions; do not use walking

       -decomposeParDictfile
              Use specified file for decomposePar dictionary

       -detectOnly
              Do not write mesh

       -insidePointpoint
              Only write region containing point

       -largestOnly
              Only write largest region

       -makeCellZones
              Place cells into cellZones instead of splitting mesh

       -overwrite
              Overwrite existing mesh/results files

       -parallel
              Run in parallel [Paralleloption]-prefixRegion
              Prefix region name to all patches, not just coupling patches

       -regionname
              Specify alternative mesh region

       -sloppyCellZones
              Try to match heuristically regions to existing cell zones

       -useFaceZones
              Use faceZones to patch inter-region faces instead of single patch

       -help  Display short help and exit

       -help-full
              Display full help and exit

   ADVANCEDOPTIONS-debug-switchname=val
              Specify the value of a registered debug switch. Default is 1 if the value is omitted. (Can be used
              multiple times)

       -fileHandlerhandler
              Override the file handler type

       -hostRoots((host1dir1)..(hostNdirN))
              Per-host  slave  root  directories for distributed running. The host specification can be a regex.
              [Paralleloption]-info-switchname=val
              Specify the value of a registered info switch. Default is 1 if the value is omitted. (Can be  used
              multiple times)

       -libname
              Additional library or library list to load (can be used multiple times)

       -opt-switchname=val
              Specify  the  value  of  a registered optimisation switch (int/bool). Default is 1 if the value is
              omitted. (Can be used multiple times)

       -roots(dir1..dirN)
              Slave root directories for distributed running [Paralleloption]-doc-source
              Display source code in browser

       -help-compat
              Display compatibility options and exit

       -help-man
              Display full help (manpage format) and exit

       -help-notes
              Display help notes (description) and exit

   COMPATIBILITYOPTIONS-noFunctionObjects
              This option is ignored
