#include <deal.II/grid/tria_faces.h>

Detailed Description

template<int dim>
class internal::TriangulationImplementation::TriaFaces< dim >

This class contains information belonging to the faces of a triangulation. These classes are similar to the TriaLevel classes. As cells are organized in a hierarchical structure of levels, each triangulation consists of several such TriaLevels. However the faces of a triangulation, lower dimensional objects like lines in 2d or lines and quads in 3d, do not have to be based on such a hierarchical structure. In fact we have to organise them in only one object if we want to enable anisotropic refinement. Therefore the TriaFaces classes store the information belonging to the faces of a triangulation separately from the TriaLevel classes.

Constructor & Destructor Documentation

TriaFaces() [1/2]

template<int dim>

internal::TriangulationImplementation::TriaFaces< dim >::TriaFaces	(	const unsigned int	max_children_per_quad,
		const unsigned int	max_lines_per_quad
	)

Constructor.

Parameters

[in]	max_children_per_quad	Maximum number of children (across all relevant ReferenceCell types) a quad (i.e., a face of a cell in 3d) in the present Triangulation may have. Only used in 3d.
[in]	max_lines_per_quad	Maximum number of faces (i.e., neighbors) per cell. Like max_children_per_quad, this is the maximum over all relevant ReferenceCell types and is only used in 2d and 3d.

Definition at line 35 of file tria_faces.cc.

TriaFaces() [2/2]

template<int dim>

internal::TriangulationImplementation::TriaFaces< dim >::TriaFaces ( )

default

Default constructor for Boost::serialization.

Member Function Documentation

allocate()

template<int dim>

void internal::TriangulationImplementation::TriaFaces< dim >::allocate	(	const std::size_t	n_lines,
		const std::size_t	n_quads
	)

Resize all internal arrays and populate with default values.

Definition at line 48 of file tria_faces.cc.

allocate_end()

template<int dim>

void internal::TriangulationImplementation::TriaFaces< dim >::allocate_end	(	const std::size_t	new_quads_in_pairs,
		const std::size_t	new_quads_single
	)

Allocate space at the end of each array for new quads and populate the new values with default values.

Parameters

[in]	new_quads_in_pairs	Number of new quads which should be added as pairs.
[in]	new_quads_single	Number of new quads which should be added alone (i.e., not in pairs).

Note

If dim < 3 then this function does nothing.

Member Data Documentation

lines_per_quad

template<int dim>

unsigned int internal::TriangulationImplementation::TriaFaces< dim >::lines_per_quad

Number of lines for each quad (i.e., face of a 3d cell). Only used for dim == 3.

Definition at line 91 of file tria_faces.h.

quads

template<int dim>

TriaObjects internal::TriangulationImplementation::TriaFaces< dim >::quads

The TriaObject containing the data of quads.

Note

Used only for dim=3.

Definition at line 98 of file tria_faces.h.

lines

template<int dim>

TriaObjects internal::TriangulationImplementation::TriaFaces< dim >::lines

The TriaObject containing the data of lines.

Note

Used only for dim>1.

Definition at line 136 of file tria_faces.h.

quad_is_quadrilateral

template<int dim>

std::vector<bool> internal::TriangulationImplementation::TriaFaces< dim >::quad_is_quadrilateral

private

Whether or not each quad is a Quadrilateral. Since, if dim = 3, faces are either Triangles or Quadrilaterals, it suffices to store a boolean.

Note

Used only for dim=3.

Definition at line 162 of file tria_faces.h.

quads_line_orientations

template<int dim>

std::vector<bool> internal::TriangulationImplementation::TriaFaces< dim >::quads_line_orientations

private

Orientation of each line of each quad. Like elsewhere, true refers to the standard orientation and false refers to the reverse orientation.

Note

Used only for dim=3.
