Function Documentation

cells() [1/2]

void cells	(	la::SparsityPattern &	pattern,
		const mesh::Topology &	topology,
		const std::array< const std::reference_wrapper< const DofMap >, 2 > &	dofmaps
	)

Parameters

[in,out]	pattern	The sparsity pattern to insert into
[in]	topology	The mesh topology to build the sparsity pattern over
[in]	dofmaps	The dofmap to use in building the sparsity pattern

Note

The sparsity pattern is not finalised
