Detailed Description

template<int dim, int spacedim = dim>
class RepartitioningPolicyTools::MinimalGranularityPolicy< dim, spacedim >

A policy that allows to specify a minimal number of cells per process. If a threshold is reached, processes might be left without cells. The cells will be distributed evenly among the remaining processes.
