Detailed Description

Stores the cells of a mesh (low-level store)

Definition at line 1530 of file mesh.h.

Member Function Documentation

◆ are_simplices()

bool GEO::MeshCellsStore::are_simplices ( ) const

inline

Tests whether all the cells are tetrahedra.

Storage and access are optimized when all the cells are tetrahedra

Return values

true	if all the cells are tetrahedra
false	otherwise

Definition at line 1541 of file mesh.h.

◆ cell_type_to_cell_descriptor()

static const CellDescriptor& GEO::MeshCellsStore::cell_type_to_cell_descriptor ( MeshCellType t )

inlinestatic

Gets a descriptor by cell type.

The descriptor of a cell is a set of static arrays that facilitate some accesses (most client code do not need to use this function)

Parameters

[in] t one of MESH_TET, MESH_HEX, MESH_PRISM, MESH_PYRAMID, MESH_CONNECTOR

Returns: the descriptor of cell c

Definition at line 1583 of file mesh.h.

◆ clear_store()

void GEO::MeshCellsStore::clear_store	(	bool	keep_attributes,
		bool	keep_memory = `false`
	)

overrideprotectedvirtual

Removes all the elements and attributes.

Parameters

[in]	keep_attributes	if true, then all the existing attribute names / bindings are kept (but they are cleared). If false, they are destroyed.
[in]	keep_memory	if true, then memory is kept and can be reused by subsequent mesh element creations.

Reimplemented from GEO::MeshSubElementsStore.

◆ corner()

index_t GEO::MeshCellsStore::corner	(	index_t	c,
		index_t	lv
	)		const

inline

Gets a corner of a cell by local vertex index.

Parameters

[in]	c	the cell, in 0..nb()-1
[in]	lv	the local vertex index, in 0..nb_corners(c)-1

Returns: the corner incident to vertex lv in cell c

Definition at line 1628 of file mesh.h.

◆ corners_begin()

index_t GEO::MeshCellsStore::corners_begin ( index_t c ) const

inline

Gets the first element for iterating over the corners of a cell.

Parameters

[in] c the cell, in 0..nb()-1

Returns: the first corner of the cell

Definition at line 1606 of file mesh.h.

◆ corners_end()

index_t GEO::MeshCellsStore::corners_end ( index_t c ) const

inline

Gets the upper limit for iterating over the corners of a cell.

Parameters

[in] c the cell, in 0..nb()-1

Returns: one position past the last corner of the cell

Definition at line 1617 of file mesh.h.

◆ descriptor()

const CellDescriptor& GEO::MeshCellsStore::descriptor ( index_t c ) const

inline

Gets the descriptor of a cell.

The descriptor of a cell is a set of static arrays that facilitate some accesses (most client code do not need to use this function)

Parameters

[in] c a cell, in 0..nb()-1

Returns: the descriptor of cell c

Definition at line 1564 of file mesh.h.

◆ facet()

index_t GEO::MeshCellsStore::facet	(	index_t	c,
		index_t	lf
	)		const

inline

Gets a facet of a cell by local facet index.

Parameters

[in]	c	the cell, in 0..nb()-1
[in]	lf	the local facet index, in 0..nb_facets(c)-1

Returns: the facet lf in cell c

Definition at line 1676 of file mesh.h.

◆ facets_begin()

index_t GEO::MeshCellsStore::facets_begin ( index_t c ) const

inline

Gets the first element for iterating over the facets of a cell.

Parameters

[in] c the cell, in 0..nb()-1

Returns: the first facet of the cell

Definition at line 1654 of file mesh.h.

◆ facets_end()

index_t GEO::MeshCellsStore::facets_end ( index_t c ) const

inline

Gets the upper limit for iterating over the facets of a cell.

Parameters

[in] c the cell, in 0..nb()-1

Returns: one position past the last facet of the facet

Definition at line 1665 of file mesh.h.

◆ nb_corners()

index_t GEO::MeshCellsStore::nb_corners ( index_t c ) const

inline

Gets the number of corners of a cell.

Parameters

[in] c a cell, in 0..nb()-1

Returns: the number of corners of cell c

Definition at line 1595 of file mesh.h.

◆ nb_edges()

index_t GEO::MeshCellsStore::nb_edges ( index_t c ) const

inline

Gets the number of edges in a cell.

Parameters

[in] c the cell, in 0..nb()-1

Returns: the number of edges in cell c

Definition at line 1687 of file mesh.h.

◆ nb_facets()

index_t GEO::MeshCellsStore::nb_facets ( index_t c ) const

inline

Gets the number of facets of a cell.

Parameters

[in] c the cell, in 0..nb()-1

Returns: the number of facets of cell c

Definition at line 1643 of file mesh.h.

◆ resize_store()

void GEO::MeshCellsStore::resize_store ( index_t new_size )

overrideprotectedvirtual

Resizes this MeshSubElementsStore.

On exit, nb() == new_size, elements are created or destroyed if needed.

Parameters

[in] new_size the desired size

Reimplemented from GEO::MeshSubElementsStore.

MeshCellType GEO::MeshCellsStore::type ( index_t c ) const

inline

Gets the type of a cell.

Parameters
