Detailed Description

Rectangle mesh creation.

Function Documentation

create() [1/2]

mesh::Mesh dolfinx::generation::RectangleMesh::create	(	MPI_Comm	comm,
		const std::array< std::array< double, 3 >, 2 > &	p,
		std::array< std::size_t, 2 >	n,
		mesh::CellType	celltype,
		const mesh::GhostMode	ghost_mode,
		const mesh::CellPartitionFunction &	partitioner,
		const std::string &	diagonal = "right"
	)

Create a uniform mesh::Mesh over the rectangle spanned by the two points p. The order of the two points is not important in terms of minimum and maximum coordinates. The total number of vertices will be (n[0] + 1)*(n[1] + 1). For triangles there will be will be 2*n[0]*n[1] cells. For quadrilaterals the number of cells will be n[0]*n[1].

Parameters

[in]	comm	MPI communicator to build the mesh on
[in]	p	Two corner points
[in]	n	Number of cells in each direction
[in]	celltype	Cell shape
[in]	ghost_mode	Mesh ghosting mode
[in]	partitioner	Partitioning function to use for determining the parallel distribution of cells across MPI ranks
[in]	diagonal	Direction of diagonals: "left", "right", "left/right", "crossed"

Returns

Mesh

create() [2/2]

mesh::Mesh dolfinx::generation::RectangleMesh::create	(	MPI_Comm	comm,
		const std::array< std::array< double, 3 >, 2 > &	p,
		std::array< std::size_t, 2 >	n,
		mesh::CellType	celltype,
		const mesh::GhostMode	ghost_mode,
		const std::string &	diagonal = "right"
	)

Create a uniform mesh::Mesh over the rectangle spanned by the two points p. The order of the two points is not important in terms of minimum and maximum coordinates. The total number of vertices will be (n[0] + 1)*(n[1] + 1). For triangles there will be will be 2*n[0]*n[1] cells. For quadrilaterals the number of cells will be n[0]*n[1].

Parameters

[in]	comm	MPI communicator to build the mesh on
[in]	p	Two corner points
[in]	n	Number of cells in each direction
[in]	celltype	Cell shape
[in]	ghost_mode	Mesh ghosting mode
[in]	diagonal	Direction of diagonals: "left", "right", "left/right", "crossed"

Returns
