Detailed Description

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

A dummy policy that simply returns an empty vector, which is interpreted in MGTransferGlobalCoarseningTools::create_geometric_coarsening_sequence() in a way that the triangulation is not repartitioned.
