Detailed Description

Dynamic mesh redistribution using the distributor specified in decomposeParDict.

Usage
Example of single field based refinement in all cells: 
distributor
{
    type            distributor;

    libs            ("libfvMeshDistributors.so");

    // How often to redistribute
    redistributionInterval  10;

    // Maximum fractional cell distribution imbalance
    // before rebalancing
    maxImbalance    0.1;
}
