Detailed Description

Automatically decomposes a mesh and fields of a case for parallel execution of OpenFOAM.

Original source file decomposePar.C

Usage

• decomposePar [OPTION]

Parameters

-cellDist	Write the cell distribution as a labelList, for use with 'manual' decomposition method or as a volScalarField for post-processing.
-region	regionName Decompose named region. Does not check for existence of processor*.
-allRegions	Decompose all regions in regionProperties. Does not check for existence of processor*.
-copyUniform	Copy any uniform directories too.
-constant
-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.
-fields	Use existing geometry decomposition and convert fields only.
-noSets	Skip decomposing cellSets, faceSets, pointSets.
-force	Remove any existing processor subdirectories before decomposing the geometry.
-ifRequired	Only decompose the geometry if the number of domains has changed from a previous decomposition. No processor subdirectories will be removed unless the -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.
-numberOfSubdomains	n Override dictionary entry decomposeParDict.numberOfSubdomains.
