Function Documentation

determine_neighbors()

template<typename T >

void internal::TriangulationImplementation::determine_neighbors	(	const CRS< T > &	con_cf,
		CRS< T > &	con_cc
	)

Determine the neighbors of all cells.

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

Definition at line 946 of file connectivity.h.

build_face_entities_templated()

template<int max_n_vertices, typename FU >

void internal::TriangulationImplementation::build_face_entities_templated	(	const unsigned int	face_dimensionality,
		const std::vector< std::shared_ptr< CellTypeBase > > &	cell_types,
		const std::vector< ReferenceCell > &	cell_types_index,
		const CRS< unsigned int > &	crs,
		CRS< unsigned int > &	crs_d,
		CRS< unsigned int > &	crs_0,
		TriaObjectsOrientations &	orientations,
		const FU &	second_key_function
	)

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

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

Definition at line 999 of file connectivity.h.

build_face_entities()

template<typename FU >

void internal::TriangulationImplementation::build_face_entities	(	const unsigned int	face_dimensionality,
		const std::vector< std::shared_ptr< CellTypeBase > > &	cell_types,
		const std::vector< ReferenceCell > &	cell_types_index,
		const CRS< unsigned int > &	crs,
		CRS< unsigned int > &	crs_d,
		CRS< unsigned int > &	crs_0,
		TriaObjectsOrientations &	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 1190 of file connectivity.h.

build_intersection()

void internal::TriangulationImplementation::build_intersection ( const std::vector< std::shared_ptr< CellTypeBase > > &  cell_types, const std::vector< ReferenceCell > &  cell_types_index, const CRS< unsigned int > &  con_cv, const CRS< unsigned int > &  con_cl, const CRS< unsigned int > &  con_lv, const CRS< unsigned int > &  con_cq, const CRS< unsigned int > &  con_qv, const TriaObjectsOrientations &  ori_cq, CRS< unsigned int > &  con_ql, TriaObjectsOrientations &  ori_ql, std::vector< ReferenceCell > &  quad_t_id  )

inline

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 1255 of file connectivity.h.

build_connectivity() [1/2]

template<typename T >

Connectivity< T > internal::TriangulationImplementation::build_connectivity	(	const unsigned int	dim,
		const std::vector< std::shared_ptr< CellTypeBase > > &	cell_t,
		const std::vector< ReferenceCell > &	cell_t_id,
		const CRS< T > &	con_cv
	)

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 1373 of file connectivity.h.

build_connectivity() [2/2]

template<typename T , int dim>

Connectivity< T > internal::TriangulationImplementation::build_connectivity

(

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

cells

)

Preprocessing step to remove the template argument dim.

Definition at line 1460 of file connectivity.h.

reserve_space() [1/3]

void internal::TriangulationImplementation::reserve_space	(	TriaFaces &	tria_faces,
		const unsigned int	new_quads_in_pairs,
		const unsigned int	new_quads_single
	)

Definition at line 1997 of file tria.cc.

reserve_space() [2/3]

void internal::TriangulationImplementation::reserve_space	(	TriaLevel &	tria_level,
		const unsigned int	total_cells,
		const unsigned int	dimension,
		const unsigned int	space_dimension,
		const bool	tetraheder_in_mesh = false
	)

Reserve space for TriaLevel. Details:

Reserve enough space to accommodate total_cells cells on this level. Since there are no used flags on this level, you have to give the total number of cells, not only the number of newly to accommodate ones, like in the TriaLevel<N>::reserve_space functions, with N>0.

Since the number of neighbors per cell depends on the dimensions, you have to pass that additionally.

Definition at line 2077 of file tria.cc.

monitor_memory() [1/2]

void internal::TriangulationImplementation::monitor_memory	(	const TriaLevel &	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 2199 of file tria.cc.

reserve_space() [3/3]

void internal::TriangulationImplementation::reserve_space	(	TriaObjects &	tria_objects,
		const unsigned int	new_objects_in_pairs,
		const unsigned int	new_objects_single = 0
	)

Reserve space for TriaObjects. Details:

Assert that enough space is allocated to accommodate new_objs_in_pairs new objects, stored in pairs, plus new_obj_single stored individually. This function does not only call vector::reserve(), but does really append the needed elements.

In 2d e.g. refined lines have to be stored in pairs, whereas new lines in the interior of refined cells can be stored as single lines.

Definition at line 2227 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.
