When snappyHexMesh is run in parallel it re-balances the mesh during refinement
and layer addition by redistribution which requires a decomposition method
that operates in parallel, e.g. hierachical or ptscotch. decomposePar uses a
decomposition method which operates in serial e.g. hierachical but NOT
ptscotch. In order to run decomposePar followed by snappyHexMesh in parallel it
has been necessary to change the method specified in decomposeParDict but now
this is avoided by separately specifying the decomposition and distribution
methods, e.g. in the incompressible/simpleFoam/motorBike case:
numberOfSubdomains 6;
decomposer hierarchical;
distributor ptscotch;
hierarchicalCoeffs
{
n (3 2 1);
order xyz;
}
The distributor entry is also used for run-time mesh redistribution, e.g. in the
multiphase/interFoam/RAS/floatingObject case re-distribution for load-balancing
is enabled in constant/dynamicMeshDict:
distributor
{
type distributor;
libs ("libfvMeshDistributors.so");
redistributionInterval 10;
}
which uses the distributor specified in system/decomposeParDict:
distributor hierarchical;
This rationalisation provides the structure for development of mesh
redistribution and load-balancing.

decomposePar
|
|
|
|
Description
|
|
Automatically decomposes a mesh and fields of a case for parallel
|
|
execution of OpenFOAM.
|
|
|
|
Usage
|
|
\b decomposePar [OPTION]
|
|
|
|
Options:
|
|
- \par -cellDist
|
|
Write the cell distribution as a labelList, for use with 'manual'
|
|
decomposition method or as a volScalarField for post-processing.
|
|
|
|
- \par -region \<regionName\> \n
|
|
Decompose named region. Does not check for existence of processor*.
|
|
|
|
- \par -allRegions \n
|
|
Decompose all regions in regionProperties. Does not check for
|
|
existence of processor*.
|
|
|
|
- \par -copyZero \n
|
|
Copy \a 0 directory to processor* rather than decompose the fields.
|
|
|
|
- \par -copyUniform \n
|
|
Copy any \a uniform directories too.
|
|
|
|
- \par -constant
|
|
|
|
- \par -time xxx:yyy \n
|
|
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 \n
|
|
Use existing geometry decomposition and convert fields only.
|
|
|
|
- \par -noSets \n
|
|
Skip decomposing cellSets, faceSets, pointSets.
|
|
|
|
- \par -force \n
|
|
Remove any existing \a processor subdirectories before decomposing the
|
|
geometry.
|
|
|
|
- \par -ifRequired \n
|
|
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.
|
|
|
|
- \par -dict \<filename\>
|
|
Specify alternative dictionary for the decomposition.
