Basic support is now provided for dynamic mesh redistribution, particularly for
load-balancing. The mesh distributor is selected in the optional 'distributor'
entry in dynamicMeshDict, for example in the
multiphase/interFoam/RAS/floatingObject tutorial case when run in parallel using
the new Allrun-parallel script
distributor
{
type decomposer;
libs ("libfvMeshDistributors.so");
redistributionInterval 10;
}
in which the 'decomposer' form of redistribution is selected to call the mesh
decomposition method specified in decomposeParDict to re-decompose the mesh for
redistribution. The redistributionInterval entry specifies how frequently mesh
redistribution takes place, in the above every 10th time-step. An optional
maxImbalance entry is also provided to control redistribution based on the cell
distribution imbalance:
Class
Foam::fvMeshDistributor::decomposer
Description
Dynamic mesh redistribution using the decomposer
Usage
Example of single field based refinement in all cells:
\verbatim
distributor
{
type decomposer;
libs ("libfvMeshDistributors.so");
// How often to redistribute
redistributionInterval 10;
// Maximum fractional cell distribution imbalance
// before rebalancing
maxImbalance 0.1;
}
\endverbatim
Currently mesh refinement/unrefinement and motion with redistribution is
supported but many aspects of OpenFOAM are not yet and will require further
development, in particular fvModels and Lagrangian.
Also only the geometry-based simple and hierarchical decomposition method are
well behaved for redistribution, scotch and ptScotch cause dramatic changes in
mesh distribution with a corresponding heavy communications overhead limiting
their usefulness or at least the frequency with which they should be called to
redistribute the mesh.
