decomposePar
Group
grpParallelUtilities
Description
Automatically decomposes a mesh and fields of a case for parallel
execution of OpenFOAM.
Usage
\b decomposePar [OPTION]
Options:
- \par -dry-run
Test without actually decomposing
- \par -cellDist
Write the cell distribution as a labelList, for use with 'manual'
decomposition method and as a volScalarField for visualization.
- \par -region \<regionName\>
Decompose named region. Does not check for existence of processor*.
- \par -allRegions
Decompose all regions in regionProperties. Does not check for
existence of processor*.
- \par -copyZero
Copy \a 0 directory to processor* rather than decompose the fields.
- \par -copyUniform
Copy any \a uniform directories too.
- \par -constant
- \par -time xxx:yyy
Override controlDict settings and decompose selected times. Does not
re-decompose the mesh i.e. does not handle moving mesh or changing
mesh cases.
- \par -fields
Use existing geometry decomposition and convert fields only.
- \par -noSets
Skip decomposing cellSets, faceSets, pointSets.
- \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.
