This method waits until all the threads have completed IO operations and then clears any cached information about the files on disk. This replaces the deactivation of threading by means of zeroing the buffer size when writing and reading of a file happen in sequence. It also allows paraFoam to update the list of available times.

|
|
|
|
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.
