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
