Function Documentation

void smith::mfem_ext::GetEssentialTrueDofsFromElementAttribute	(	const mfem::ParFiniteElementSpace &	fespace,
		const mfem::Array< int > &	elem_attr_is_ess,
		mfem::Array< int > &	ess_tdof_list,
		int	component = `-1`
	)

Get a list of essential true dofs, ess_tdof_list , corresponding to the element attributes marked in the array elem_attr_is_ess.

Parameters

[in]	fespace	The parallel finite element space
[in]	elem_attr_is_ess	An mfem::Array which indicates whether each element attribute is essential (the length must equal the number of attributes defined on the mesh)
[out]	ess_tdof_list	An mfem::Array containing all the true dofs
[in]	component	An optional argument denoting which component (of a vector space) is essential, -1 implies all components

void smith::mfem_ext::GetEssentialVDofsFromElementAttribute	(	const mfem::ParFiniteElementSpace &	fespace,
		const mfem::Array< int > &	elem_attr_is_ess,
		mfem::Array< int > &	ess_vdofs,
		int	component = `-1`
	)

A method to mark degrees of freedom associated with elements with the attributes specified in element_attr_is_ess.

Parameters

[in]	fespace	The parallel finite element space
[in]	elem_attr_is_ess	An mfem::Array which indicates whether each element attribute is essential (the length must equal the number of attributes defined on the mesh)
[out]	ess_vdofs	An mfem::Array marking the degrees of freedom
[in]	component	An optional argument denoting which component (of a vector space) is essential, -1 implies all components
