Member Data Documentation

block_solution_transfer

template<unsigned int dim, typename number>

std::vector<SolutionTransfer> GroupSolutionHandler< dim, number >::block_solution_transfer

private

Utility for solution transfer to different mesh (for AMR). Can only work on one block at a time.

Note

solution transfers can work on multiple solutions as long as they are using the same underlying dof numbering. All of our scalars and vectors have identical dof handlers, so we may be able to take advantage of this instead of creating several solution transfers as we do here. I don't know if this affects performance. todo

block_to_global_index

template<unsigned int dim, typename number>

std::vector<unsigned int> GroupSolutionHandler< dim, number >::block_to_global_index

private

Mapping from block index to global field index.

global_to_block_index

template<unsigned int dim, typename number>

std::vector<unsigned int> GroupSolutionHandler< dim, number >::global_to_block_index

private

Mapping from global field index to block index.

solution_levels

template<unsigned int dim, typename number>

std::vector<SolutionLevel<dim, number> > GroupSolutionHandler< dim, number >::solution_levels

private

Solutions and matrix free of each level.

solve_block

template<unsigned int dim, typename number>

SolveBlock GroupSolutionHandler< dim, number >::solve_block

private

Information about the solve block this handler is responsible for.
