Detailed Description

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

Original source file decomposePar.C

Usage

decomposePar [OPTION]

Options:

• -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*.

• -copyZero

  Copy 0 directory to processor* rather than decompose the fields.

• -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.

• -dict <filename>

  Specify alternative dictionary for the decomposition.
