Detailed Description

Mesh refinement algorithms.

Methods for refining meshes uniformly, or with markers, using edge bisection.

Function Documentation

mesh::Mesh dolfinx::refinement::refine	(	const mesh::Mesh &	mesh,
		bool	redistribute = `true`
	)

Create uniformly refined mesh.

Parameters

[in]	mesh	The mesh from which to build a refined Mesh
[in]	redistribute	Optional argument to redistribute the refined mesh if mesh is a distributed mesh.

mesh::Mesh dolfinx::refinement::refine	(	const mesh::Mesh &	mesh,
		const mesh::MeshTags< std::int8_t > &	cell_markers,
		bool	redistribute = `true`
	)

Create locally refined mesh.

Parameters

[in]	mesh	The mesh from which to build a refined Mesh
[in]	cell_markers	A mesh function over integers specifying which cells should be refined (value == 1) (and which should not (any other integer value)).
[in]	redistribute	Optional argument to redistribute the refined mesh if mesh is a distributed mesh.
