decomposePar
|
|
|
|
Description
|
|
Automatically decomposes a mesh and fields of a case for parallel
|
|
execution of OpenFOAM.
|
|
|
|
Usage
|
|
|
|
- decomposePar [OPTION]
|
|
|
|
@param -cellDist \n
|
|
Write the cell distribution as a labelList for use with 'manual'
|
|
decomposition method and as a volScalarField for post-processing.
|
|
|
|
@param -copyUniform \n
|
|
Copy any @a uniform directories too.
|
|
|
|
@param -fields \n
|
|
Use existing geometry decomposition and convert fields only.
|
|
|
|
@param -filterPatches \n
|
|
Remove empty patches when decomposing the geometry.
|
|
|
|
@param -force \n
|
|
Remove any existing @a processor subdirectories before decomposing the
|
|
geometry. Has precedence over the @a -lazy option.
|
|
|
|
@param -lazy \n
|
|
Only decompose the geometry if the number of domains has changed
|
|
from a previous decomposition. Any existing @a processor subdirectories
|
|
are removed as necessary. 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.
