Class
Foam::fvMeshDistributors::loadBalancer
Description
Dynamic mesh redistribution using the distributor specified in
decomposeParDict
Usage
Example of single field based refinement in all cells:
\verbatim
distributor
{
type loadBalancer;
libs ("libfvMeshDistributors.so");
// How often to redistribute
redistributionInterval 10;
// Maximum fractional cell distribution imbalance
// before rebalancing
maxImbalance 0.1;
}
\endverbatim
