Implementation of matrix generation for component wise multigrid transfer.
Definition at line 59 of file mg_transfer_component.h.
| std::size_t MGTransferComponentBase::memory_consumption | ( | ) | const |
Memory used by this object.
Reimplemented in MGTransferSelect< number >.
| void MGTransferComponentBase::build_matrices | ( | const DoFHandler< dim, spacedim > & | dof, |
| const MGDoFHandler< dim, spacedim > & | mg_dof | ||
| ) | [protected] |
Actually build the prolongation matrices for each level.
This function is only called by derived classes. These can also set the member variables selected and mg_selected to restrict the transfer matrices to certain components. Furthermore, they use target_component and mg_target_component for re-ordering and grouping of components.
| ::ExceptionBase& MGTransferComponentBase::ExcMatricesNotBuilt | ( | ) | [static, protected] |
Call build_matrices() function first.
std::vector<bool> MGTransferComponentBase::selected [protected] |
Flag of selected components.
The transfer operators only act on the components having a true entry here. If renumbering by target_component is used, this refers to the renumbered components.
Definition at line 100 of file mg_transfer_component.h.
std::vector<bool> MGTransferComponentBase::mg_selected [protected] |
Flag of selected components.
The transfer operators only act on the components having a true entry here. If renumbering by mg_target_component is used, this refers to the renumbered components.
Definition at line 113 of file mg_transfer_component.h.
std::vector<unsigned int> MGTransferComponentBase::target_component [protected] |
Target component of the fine-level vector if renumbering is required.
Definition at line 120 of file mg_transfer_component.h.
std::vector<unsigned int> MGTransferComponentBase::mg_target_component [protected] |
Target component if renumbering of level vectors is required.
Definition at line 127 of file mg_transfer_component.h.
std::vector<std::vector<unsigned int> > MGTransferComponentBase::sizes [mutable, protected] |
Sizes of the multi-level vectors.
Definition at line 132 of file mg_transfer_component.h.
std::vector<unsigned int> MGTransferComponentBase::component_start [protected] |
Start index of each component.
Definition at line 137 of file mg_transfer_component.h.
std::vector<std::vector<unsigned int> > MGTransferComponentBase::mg_component_start [protected] |
Start index of each component on all levels.
Definition at line 143 of file mg_transfer_component.h.
std::vector<std_cxx1x::shared_ptr<BlockSparsityPattern> > MGTransferComponentBase::prolongation_sparsities [private] |
Definition at line 152 of file mg_transfer_component.h.
std::vector<std_cxx1x::shared_ptr<BlockSparseMatrix<double> > > MGTransferComponentBase::prolongation_matrices [protected] |
The actual prolongation matrix. column indices belong to the dof indices of the mother cell, i.e. the coarse level. while row indices belong to the child cell, i.e. the fine level.
Definition at line 164 of file mg_transfer_component.h.
std::vector<std::vector<std::pair<unsigned int, unsigned int> > > MGTransferComponentBase::copy_to_and_from_indices [protected] |
Holds the mapping for the copy_to/from_mg-functions. The data is first the global index, then the level index.
Definition at line 173 of file mg_transfer_component.h.
std::vector<std::set<unsigned int> > MGTransferComponentBase::boundary_indices [protected] |
Store the boundary_indices. These are needed for the boundary values in the restriction matrix.
Definition at line 181 of file mg_transfer_component.h.
