Member Function Documentation

template<typename TreeGrid>

auto hm3::grid::adaptor::multi< TreeGrid >::refine ( tree_node_idx  n )

noexcept

Refines node n and return the tree_node_idx of its children.

If p has children, this just return the children. Otherwise, it refines the node within the tree.

template<typename TreeGrid>

auto hm3::grid::adaptor::multi< TreeGrid >::remove ( tree_node_idx  n, grid_idx  g  )

noexcept

Remove grid node of grid g at node n.

If the siblings of node n are leafs and contain no grid nodes from any grid they will be removed from the tree (their parent will be coarsen).
