Input mesh to be refined

Returns

New mesh data: cell topology, vertex coordinates and parent cell index

compute_refinement_data() [2/2]

std::tuple< graph::AdjacencyList< std::int64_t >, xt::xtensor< double, 2 >, std::vector< std::int32_t > > dolfinx::refinement::plaza::compute_refinement_data	(	const mesh::Mesh &	mesh,
		const mesh::MeshTags< std::int8_t > &	refinement_marker
	)

Refine with markers returning new mesh data.

Parameters

[in]	mesh	Input mesh to be refined
[in]	refinement_marker	MeshTags listing which mesh entities should be split by this refinement. The values are ignored. redistribute after refinement

Returns

New mesh data: cell topology, vertex coordinates and parent cell index

refine() [1/2]

mesh::Mesh dolfinx::refinement::plaza::refine	(	const mesh::Mesh &	mesh,
		bool	redistribute
	)

Uniform refine, optionally redistributing and optionally calculating the parent-child relation for facets (in 2D)

Parameters

[in]	mesh	Input mesh to be refined
[in]	redistribute	Flag to call the mesh partitioner to redistribute after refinement

Returns

New mesh

[in]	refinement_marker	MeshTags listing which mesh entities should be split by this refinement. The values are ignored.
[in]	redistribute	Flag to call the Mesh Partitioner to redistribute after refinement

Returns

New Mesh
