Detailed Description

Redistributes existing decomposed mesh and fields according to the current settings in the decomposeParDict file.

Must be run on maximum number of source and destination processors. Balances mesh and writes new mesh to new time directory.

Can also work like decomposePar:

# Create empty processors mkdir processor0 .. mkdir processorN

# Copy undecomposed polyMesh cp -r constant processor0

# Distribute mpirun -np ddd redistributeMeshPar -parallel

Note:

You might want to unset FOAM_SIGFPE and FOAM_SETNAN since patchfields that hold additional data might not be initialised (since mapped from 0 faces)

Usage

• redistributeMeshPar [OPTIONS]

Parameters:

-mergeTol	<number> Relative merge distance.
-case	<dir> Case directory.
-parallel	Run in parallel.
-help	Display help message.
-doc	Display Doxygen API documentation page for this application.
