Detailed Description

A namespace for classes internal to the triangulation classes and helpers.

Function Documentation

monitor_memory() [1/2]

template<int dim, int spacedim>

void internal::TriangulationImplementation::monitor_memory	(	const TriaLevel< dim, spacedim > &	tria_level,
		const unsigned int	true_dimension )

Check the memory consistency of the different containers. Should only be called with the preprocessor flag DEBUG set. The function should be called from the functions of the higher TriaLevel classes.

Definition at line 2073 of file tria.cc.

monitor_memory() [2/2]

void internal::TriangulationImplementation::monitor_memory	(	const TriaObjects &	tria_object,
		const unsigned int	)

Check the memory consistency of the different containers. Should only be called with the preprocessor flag DEBUG set. The function should be called from the functions of the higher TriaLevel classes.

Definition at line 2094 of file tria.cc.

determine_neighbors()

ArrayOfArrays internal::TriangulationImplementation::determine_neighbors

(

const ArrayOfArrays &

cells_to_faces

)

Determine the neighbors of all cells.

con_cf connectivity cell-face

Returns

connectivity cell-cell (for each cell-face it contains the index of the neighboring cell or -1 for boundary face)

Definition at line 2514 of file tria.cc.

build_face_entities_templated()

template<int max_n_vertices, int face_dim, int dim, typename FU>

void internal::TriangulationImplementation::build_face_entities_templated	(	const std::vector< ReferenceCell< dim > > &	cell_types,
		const ArrayOfArrays &	cells_to_vertices,
		ArrayOfArrays &	cells_to_faces,
		ArrayOfArrays &	crs_0,
		std::vector< types::geometric_orientation > &	orientations,
		const FU &	second_key_function )

Build entities of dimension face_dim (with 0<face_dim<dim). Entities are described by a set of vertices.

Furthermore, the function determines for each cell of which face_dim-dimensional entity it consists of and its orientation relative to the cell.

Definition at line 2589 of file tria.cc.

build_face_entities()

template<int face_dim, int dim, typename FU>

void internal::TriangulationImplementation::build_face_entities	(	const std::vector< ReferenceCell< dim > > &	cell_types,
		const ArrayOfArrays &	cells_to_vertices,
		ArrayOfArrays &	cells_to_faces,
		ArrayOfArrays &	crs_0,
		std::vector< types::geometric_orientation > &	orientations,
		const FU &	second_key_function )

Call the right templated function to be able to use std::array instead of std::vector.

Definition at line 2805 of file tria.cc.

build_intersection()

template<int dim>

void internal::TriangulationImplementation::build_intersection	(	const std::vector< ReferenceCell< dim > > &	cell_types,
		const ArrayOfArrays &	cells_to_vertices,
		const ArrayOfArrays &	cells_to_lines,
		const ArrayOfArrays &	lines_to_vertices,
		const ArrayOfArrays &	cells_to_quads,
		const ArrayOfArrays &	quads_to_vertices,
		const std::vector< types::geometric_orientation > &	ori_cq,
		ArrayOfArrays &	quads_to_lines,
		std::vector< types::geometric_orientation > &	ori_ql,
		std::vector< ReferenceCell< 2 > > &	quad_t_id )

Build surface lines described by:

• connectivity quad -> line
• orientation of line relative to the quad

Furthermore, the type of the quad is determined.

Definition at line 2865 of file tria.cc.

build_connectivity() [1/2]

template<int dim>

Connectivity< dim > internal::TriangulationImplementation::build_connectivity	(	const std::vector< ReferenceCell< dim > > &	cell_types,
		const std::set< ReferenceCell< dim > > &	all_reference_cells,
		const ArrayOfArrays &	cells_to_vertices )

Build the reduced connectivity table for the given dimension dim.

This function is inspired by the publication Anders Logg "Efficient Representation of Computational Meshes" and the FEniCS's DOLFIN mesh implementation. It has been strongly adjusted to efficiently solely meet our connectivity needs while sacrificing some of the flexibility there.

Definition at line 2980 of file tria.cc.

build_connectivity() [2/2]

template<int dim>

Connectivity< dim > internal::TriangulationImplementation::build_connectivity

(

const std::vector< CellData< dim > > &

cells

)

Preprocessing step to remove the template argument dim.
