MGTwoLevelTransfer< dim, VectorType >::MGTransferScheme Struct Reference

Detailed Description

template<int dim, typename VectorType>
struct MGTwoLevelTransfer< dim, VectorType >::MGTransferScheme

A multigrid transfer scheme. A multrigrid transfer class can have different transfer schemes to enable p-adaptivity (one transfer scheme per polynomial degree pair) and to enable global coarsening (one transfer scheme for transfer between children and parent cells, as well as, one transfer scheme for cells that are not refined).

Member Data Documentation

n_coarse_cells

template<int dim, typename VectorType >

unsigned int MGTwoLevelTransfer< dim, VectorType >::MGTransferScheme::n_coarse_cells

Number of coarse cells.

Definition at line 537 of file mg_transfer_matrix_free.h.

n_dofs_per_cell_coarse

template<int dim, typename VectorType >

unsigned int MGTwoLevelTransfer< dim, VectorType >::MGTransferScheme::n_dofs_per_cell_coarse

Number of degrees of freedom of a coarse cell.

Note

For tensor-product elements, the value equals n_components * (degree_coarse + 1)^dim.

Definition at line 545 of file mg_transfer_matrix_free.h.

n_dofs_per_cell_fine

template<int dim, typename VectorType >

unsigned int MGTwoLevelTransfer< dim, VectorType >::MGTransferScheme::n_dofs_per_cell_fine

Number of degrees of freedom of fine cell.

Note

For tensor-product elements, the value equals n_components * (n_dofs_per_cell_fine + 1)^dim.

Definition at line 553 of file mg_transfer_matrix_free.h.

degree_coarse

template<int dim, typename VectorType >

unsigned int MGTwoLevelTransfer< dim, VectorType >::MGTransferScheme::degree_coarse

Polynomial degree of the finite element of a coarse cell.

Definition at line 558 of file mg_transfer_matrix_free.h.

degree_fine

template<int dim, typename VectorType >

unsigned int MGTwoLevelTransfer< dim, VectorType >::MGTransferScheme::degree_fine

"Polynomial degree" of the finite element of the union of all children of a coarse cell, i.e., actually degree_fine * 2 + 1 if a cell is refined.

Definition at line 565 of file mg_transfer_matrix_free.h.

prolongation_matrix

template<int dim, typename VectorType >

AlignedVector<double> MGTwoLevelTransfer< dim, VectorType >::MGTransferScheme::prolongation_matrix

Prolongation matrix used for the prolongate_and_add() and restrict_and_add() functions.

Definition at line 571 of file mg_transfer_matrix_free.h.

restriction_matrix

template<int dim, typename VectorType >

AlignedVector<double> MGTwoLevelTransfer< dim, VectorType >::MGTransferScheme::restriction_matrix

Restriction matrix used for the interpolate() function.

Definition at line 576 of file mg_transfer_matrix_free.h.

shape_info_coarse

template<int dim, typename VectorType >

internal::MatrixFreeFunctions::ShapeInfo<double> MGTwoLevelTransfer< dim, VectorType >::MGTransferScheme::shape_info_coarse

ShapeInfo description of the coarse cell. Needed during the fast application of hanging-node constraints.
