Member Function Documentation

initialize()

template<int dim, typename Number>

void internal::MatrixFreeFunctions::MappingInfo< dim, Number >::initialize	(	const ::Triangulation< dim > &	tria,
		const std::vector< std::pair< unsigned int, unsigned int > > &	cells,
		const FaceInfo< VectorizedArray< Number >::n_array_elements > &	faces,
		const std::vector< unsigned int > &	active_fe_index,
		const Mapping< dim > &	mapping,
		const std::vector<::hp::QCollection< 1 > > &	quad,
		const UpdateFlags	update_flags_cells,
		const UpdateFlags	update_flags_boundary_faces,
		const UpdateFlags	update_flags_inner_faces,
		const UpdateFlags	update_flags_faces_by_cells
	)

Compute the information in the given cells and faces. The cells are specified by the level and the index within the level (as given by CellIterator::level() and CellIterator::index(), in order to allow for different kinds of iterators, e.g. standard DoFHandler, multigrid, etc.) on a fixed Triangulation. In addition, a mapping and several quadrature formulas are given.

get_cell_type()

template<int dim, typename Number >

GeometryType internal::MatrixFreeFunctions::MappingInfo< dim, Number >::get_cell_type ( const unsigned int  cell_chunk_no ) const

inline

Return the type of a given cell as detected during initialization.

Definition at line 498 of file mapping_info.h.

clear()

template<int dim, typename Number>

void internal::MatrixFreeFunctions::MappingInfo< dim, Number >::clear

(

)

Clear all data fields in this class.

memory_consumption()

template<int dim, typename Number>

std::size_t internal::MatrixFreeFunctions::MappingInfo< dim, Number >::memory_consumption

(

)

const

Return the memory consumption of this class in bytes.

print_memory_consumption()

template<int dim, typename Number>

template<typename StreamType >

void internal::MatrixFreeFunctions::MappingInfo< dim, Number >::print_memory_consumption	(	StreamType &	out,
		const TaskInfo &	task_info
	)		const

Prints a detailed summary of memory consumption in the different structures of this class to the given output stream.

initialize_cells()

template<int dim, typename Number>

void internal::MatrixFreeFunctions::MappingInfo< dim, Number >::initialize_cells	(	const ::Triangulation< dim > &	tria,

		const Mapping< dim > &	mapping,
		const std::vector<::hp::QCollection< 1 > > &	quad,
		const UpdateFlags	update_flags_cells
	)

Computes the information in the given cells, called within initialize.

initialize_faces()

		const Mapping< dim > &	mapping,
		const std::vector<::hp::QCollection< 1 > > &	quad,
		const UpdateFlags	update_flags_boundary_faces,
		const UpdateFlags	update_flags_inner_faces
	)

Computes the information in the given faces, called within initialize.

initialize_faces_by_cells()

template<int dim, typename Number>

void internal::MatrixFreeFunctions::MappingInfo< dim, Number >::initialize_faces_by_cells	(	const ::Triangulation< dim > &	tria,
		const std::vector< std::pair< unsigned int, unsigned int > > &	cells,
		const Mapping< dim > &	mapping,
		const std::vector<::hp::QCollection< 1 > > &	quad,
		const UpdateFlags	update_flags_faces_by_cells
	)

Computes the information in the given faces, called within initialize.

compute_update_flags()

template<int dim, typename Number>

static UpdateFlags internal::MatrixFreeFunctions::MappingInfo< dim, Number >::compute_update_flags ( const UpdateFlags  update_flags, const std::vector<::hp::QCollection< 1 > > &  quad = std::vector<::hp::QCollection< 1 > >()  )

static

Helper function to determine which update flags must be set in the internal functions to initialize all data as requested by the user.

Member Data Documentation

cell_type

template<int dim, typename Number>

std::vector<GeometryType> internal::MatrixFreeFunctions::MappingInfo< dim, Number >::cell_type

Stores whether a cell is Cartesian (cell type 0), has constant transform data (Jacobians) (cell type 1), or is general (cell type 3). Type 2 is only used for faces and no cells are assigned this value.

Definition at line 337 of file mapping_info.h.

face_type

template<int dim, typename Number>

std::vector<GeometryType> internal::MatrixFreeFunctions::MappingInfo< dim, Number >::face_type

Stores whether a face (and both cells adjacent to the face) is Cartesian (face type 0), whether it represents an affine situation (face type 1), whether it is a flat face where the normal vector is the same throughout the face (face type 2), or is general (face type 3).

Definition at line 346 of file mapping_info.h.

cell_data

template<int dim, typename Number>

std::vector<MappingInfoStorage<dim,dim,Number> > internal::MatrixFreeFunctions::MappingInfo< dim, Number >::cell_data

The data cache for the cells.

Definition at line 351 of file mapping_info.h.

face_data

template<int dim, typename Number>

std::vector<MappingInfoStorage<dim-1,dim,Number> > internal::MatrixFreeFunctions::MappingInfo< dim, Number >::face_data

The data cache for the faces.

Definition at line 356 of file mapping_info.h.

face_data_by_cells

template<int dim, typename Number>

std::vector<MappingInfoStorage<dim-1,dim,Number> > internal::MatrixFreeFunctions::MappingInfo< dim, Number >::face_data_by_cells

The data cache for the face-associated-with-cell topology, following the cell_type variable for the cell types.
