Detailed Description

The class MeshData is a container for auxiliary mesh data, represented either as arrays or maps. Each dataset is identified by a unique user-specified string. Only std::size_t-valued data are currently supported.

Auxiliary mesh data may be attached to a mesh by users as a convenient way to store data associated with a mesh. It is also used internally by DOLFIN to communicate data associated with meshes. The following named mesh data are recognized by DOLFIN:

Facet orientation (used for assembly over interior facets)

• "facet_orientation" - std:vector <std::size_t> of dimension D - 1

Sub meshes (used by the class SubMesh)

• "parent_vertex_indices" - std::vector <std::size_t> of dimension 0

Note to developers: use underscore in names in place of spaces.

Member Function Documentation

std::vector< std::size_t > & MeshData::array	(	std::string	name,
		std::size_t	dim
	)

Return array with given name (returning zero if data is not available)

Parameters

name	(std::string) The name of the array.
dim	(std::size_t) Dimension.

Returns

std::vector<std::size_t> The array.

const std::vector< std::size_t > & MeshData::array	(	std::string	name,
		std::size_t	dim
	)		const

Return array with given name (returning zero if data is not available)

Parameters

name	(std::string) The name of the array.
dim	(std::size_t) Dimension.

Returns

std::vector<std::size_t> The array.

std::vector< std::size_t > & MeshData::create_array	(	std::string	name,
		std::size_t	dim
	)

Create array (vector) with given name and size

Parameters

name	(std::string) The name of the array.
dim	(std::size_t) Dimension.

Returns

std::vector<std::size_t> The array.

void MeshData::erase_array	(	const std::string	name,
		std::size_t	dim
	)

Erase array with given name

Parameters

name	(std::string) The name of the array.
dim	(std::size_t) Dimension.

bool MeshData::exists	(	std::string	name,
		std::size_t	dim
	)		const

Check is array exists

Parameters

name	(std::string) The name of the array.
dim	(std::size_t)

Returns

bool True is array exists, false otherwise.

const MeshData & MeshData::operator=

(

const MeshData &

data

)

Assignment operator

Parameters

data	(MeshData) Another MeshData object.

std::string MeshData::str ( bool  verbose ) const

virtual

Return informal string representation (pretty-print)

Parameters

verbose

(bool) Flag to turn on additional output.

Returns

std::string An informal representation.
