|
|
|
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 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 volScalarField.
|
|
|
|
- \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.
