Detailed Description

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

A policy that partitions coarse grids based on a base triangulation according to a first-child policy. The triangulation to be partitioned should be able to be obtained by a sequence of (global) coarsening steps.

Member Data Documentation

n_coarse_cells

template<int dim, int spacedim = dim>

const unsigned int RepartitioningPolicyTools::FirstChildPolicy< dim, spacedim >::n_coarse_cells

private

Number of coarse cells.

Definition at line 112 of file repartitioning_policy_tools.h.

n_global_levels

template<int dim, int spacedim = dim>

const unsigned int RepartitioningPolicyTools::FirstChildPolicy< dim, spacedim >::n_global_levels

private

Number of global levels.

is_level_partitions

template<int dim, int spacedim = dim>

IndexSet RepartitioningPolicyTools::FirstChildPolicy< dim, spacedim >::is_level_partitions

private
