Mark Olesen ca25929372 ENH: minor simplifications for handling region meshes
- static version of polyMesh::meshDir(), which takes a region name

      polyMesh::meshDir(regionName)
  vs
      polyMesh::regionName(regionName)/polyMesh::meshSubDir

STYLE: use polyMesh::regionName(..) instead of comparing to defaultRegion

STYLE: use getOrDefault when retrieving various -region options

FIX: polyMesh::dbDir() now checks registry name, not full path (#3033)

decomposePar
Group
grpParallelUtilities
Description
Automatically decomposes a mesh and fields of a case for parallel
execution of OpenFOAM.
Usage
\b decomposePar [OPTIONS]
Options:
- \par -allRegions
Decompose all regions in regionProperties. Does not check for
existence of processor*.
- \par -case \<dir\>
Specify case directory to use (instead of the cwd).
- \par -cellDist
Write the cell distribution as a labelList, for use with 'manual'
decomposition method and as a VTK or volScalarField for visualization.
- \par -constant
Include the 'constant/' dir in the times list.
- \par -copyUniform
Copy any \a uniform directories too.
- \par -copyZero
Copy \a 0 directory to processor* rather than decompose the fields.
- \par -debug-switch \<name=val\>
Specify the value of a registered debug switch. Default is 1
if the value is omitted. (Can be used multiple times)
- \par -decomposeParDict \<file\>
Use specified file for decomposePar dictionary.
- \par -dry-run
Test without writing the decomposition. Changes -cellDist to
only write VTK output.
- \par -fields
Use existing geometry decomposition and convert fields only.
- \par fileHandler \<handler\>
Override the file handler type.
- \par -force
Remove any existing \a processor subdirectories before decomposing the
geometry.
- \par -ifRequired
Only decompose the geometry if the number of domains has changed from a
previous decomposition. No \a processor subdirectories will be removed
unless the \a -force option is also specified. This option can be used
to avoid redundant geometry decomposition (eg, in scripts), but should
be used with caution when the underlying (serial) geometry or the
decomposition method etc. have been changed between decompositions.
- \par -info-switch \<name=val\>
Specify the value of a registered info switch. Default is 1
if the value is omitted. (Can be used multiple times)
- \par -latestTime
Select the latest time.
- \par -lib \<name\>
Additional library or library list to load (can be used multiple times).
- \par -noFunctionObjects
Do not execute function objects.
- \par -noSets
Skip decomposing cellSets, faceSets, pointSets.
- \par -noZero
Exclude the \a 0 dir from the times list.
- \par -opt-switch \<name=val\>
Specify the value of a registered optimisation switch (int/bool).
Default is 1 if the value is omitted. (Can be used multiple times)
- \par -region \<regionName\>
Decompose named region. Does not check for existence of processor*.
- \par -time \<ranges\>
Override controlDict settings and decompose selected times. Does not
re-decompose the mesh i.e. does not handle moving mesh or changing
mesh cases. Eg, ':10,20 40:70 1000:', 'none', etc.
- \par -verbose
Additional verbosity.
- \par -doc
Display documentation in browser.
- \par -doc-source
Display source code in browser.
- \par -help
Display short help and exit.
- \par -help-man
Display full help (manpage format) and exit.
- \par -help-notes
Display help notes (description) and exit.
- \par -help-full
Display full help and exit.
