dolfinx::refinement::plaza Namespace Reference

Function in this namespace implement the refinement method described in Plaza and Carey "Local refinement of simplicial grids based on the skeleton" (Applied Numerical Mathematics 32 (2000) 195-218). More...

Enumerations
enum class	RefinementOptions : int { none = 0 , parent_cell = 1 , parent_facet = 2 , parent_cell_and_facet = 3 }
	Selection of options when refining a Mesh. parent_cell will output a list containing the local parent cell index for each new cell, parent_facet will output a list of the cell-local facet indices in the parent cell of each facet in each new cell (or -1 if no match). parent_cell_and_facet will output both datasets.

compute_refinement_data() [1/2]

std::tuple< graph::AdjacencyList< std::int64_t >, std::vector< double >, std::array< std::size_t, 2 >, std::vector< std::int32_t >, std::vector< std::int8_t > > compute_refinement_data	(	const mesh::Mesh &	mesh,
		const std::span< const std::int32_t > &	edges,
		RefinementOptions	options
	)

Refine with markers returning new mesh data.

Parameters

[in]	mesh	Input mesh to be refined
[in]	edges	Indices of the edges that should be split by this refinement
[in]	options	RefinementOptions enum to choose the computation of parent facets, parent cells. If an option is unselected, an empty list is returned.

Returns

New mesh data: cell topology, vertex coordinates and parent cell index, and stored parent facet indices (if requested).

compute_refinement_data() [2/2]

std::tuple< graph::AdjacencyList< std::int64_t >, std::vector< double >, std::array< std::size_t, 2 >, std::vector< std::int32_t >, std::vector< std::int8_t > > compute_refinement_data	(	const mesh::Mesh &	mesh,
		RefinementOptions	options
	)

Refine mesh returning new mesh data.

Parameters

[in]	mesh	Input mesh to be refined
[in]	options	RefinementOptions enum to choose the computation of parent facets, parent cells. If an option is unselected, an empty list is returned.

Returns

New mesh data: cell topology, vertex coordinates, vertex coordinates shape, and optional parent cell index, and parent facet indices.

refine() [1/2]

std::tuple< mesh::Mesh, std::vector< std::int32_t >, std::vector< std::int8_t > > refine	(	const mesh::Mesh &	mesh,
		bool	redistribute,
		RefinementOptions	options
	)

Uniform refine, optionally redistributing and optionally calculating the parent-child relationships, selected by RefinementOptions.

Parameters

[in]	mesh	Input mesh to be refined
[in]	redistribute	Flag to call the mesh partitioner to redistribute after refinement
[in]	options	RefinementOptions enum to choose the computation of parent facets, parent cells. If an option is unselected, an empty list is returned.

Returns

New Mesh and optional parent cell index, parent facet indices

		bool	redistribute,
		RefinementOptions	options
	)
