Detailed Description

Support for building sparsity patterns from degree-of-freedom maps.

Function Documentation

cells()

void cells	(	la::SparsityPattern &	pattern,
		std::span< const std::int32_t >	cells,
		std::array< std::reference_wrapper< const DofMap >, 2 >	dofmaps
	)

Iterate over cells and insert entries into sparsity pattern.

Parameters

[in,out]	pattern	The sparsity pattern to insert into
[in]	cells	The cell indices
[in]	dofmaps	Dofmaps to used in building the sparsity pattern

Note

The sparsity pattern is not finalised

interior_facets()

void interior_facets	(	la::SparsityPattern &	pattern,
		std::span< const std::int32_t >	facets,
		std::array< std::reference_wrapper< const DofMap >, 2 >	dofmaps
	)

Iterate over interior facets and insert entries into sparsity pattern.

Parameters

[in,out]	pattern	Sparsity pattern to insert into
[in]	facets	Facets as (cell0, cell1) pairs for each facet.
[in]	dofmaps	The dofmap to use in building the sparsity pattern.

Note

The sparsity pattern is not finalised.
