Enumeration Type Documentation

Option

enum class Option : int

strong

Options for data to compute during mesh refinement.

Enumerator
none	No extra data
parent_cell	Compute list with the parent cell index for each new cell
parent_facet	Compute 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	Both cell and facet parent data

Function Documentation

compute_refinement_data() [1/2]

template<std::floating_point T>

std::tuple< graph::AdjacencyList< std::int64_t >, std::vector< T >, std::array< std::size_t, 2 >, std::vector< std::int32_t >, std::vector< std::int8_t > > compute_refinement_data	(	const mesh::Mesh< T > &	mesh,
		Option	option
	)

Refine mesh returning new mesh data.

Parameters

[in]	mesh	Input mesh to be refined
[in]	option	Control computation of parent facets and 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.

compute_refinement_data() [2/2]

template<std::floating_point T>

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

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]	option	Control 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).

refine() [1/2]

template<std::floating_point T>

std::tuple< mesh::Mesh< T >, std::vector< std::int32_t >, std::vector< std::int8_t > > refine	(	const mesh::Mesh< T > &	mesh,
		bool	redistribute,
		Option	option
	)

Uniform refine, optionally redistributing and optionally calculating the parent-child relationships`.

Parameters

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

Returns

Refined mesh and optional parent cell index, parent facet indices

refine() [2/2]

template<std::floating_point T>

std::tuple< mesh::Mesh< T >, std::vector< std::int32_t >, std::vector< std::int8_t > > refine	(	const mesh::Mesh< T > &	mesh,
		std::span< const std::int32_t >	edges,
		bool	redistribute,
		Option	option
	)

Refine with markers, optionally redistributing, and optionally calculating the parent-child relationships.

Parameters

[in]	mesh	Input mesh to be refined
[in]	edges	Indices of the edges that should be split by this refinement
[in]	redistribute	Flag to call the Mesh Partitioner to redistribute after refinement
[in]	option	Control 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
