Constructor & Destructor Documentation

mfem::LORDiscretization::LORDiscretization	(	BilinearForm &	a_ho,
		const Array< int > &	ess_tdof_list,
		int	ref_type = `BasisType::GaussLobatto`
	)

Construct the low-order refined version of a_ho using the given list of essential DOFs.

The mesh is refined using the refinement type specified by ref_type (see Mesh::MakeRefined).

Definition at line 376 of file lor.cpp.

mfem::LORDiscretization::LORDiscretization	(	FiniteElementSpace &	fes_ho,
		int	ref_type = `BasisType::GaussLobatto`
	)

Construct a low-order refined version of the FiniteElementSpace fes_ho.

The mesh is refined using the refinement type specified by ref_type (see Mesh::MakeRefined).

Definition at line 384 of file lor.cpp.

void mfem::LORDiscretization::AssembleSystem	(	BilinearForm &	a_ho,
		const Array< int > &	ess_dofs
	)

Assembles the LOR system corresponding to a_ho.

Definition at line 407 of file lor.cpp.

SparseMatrix & mfem::LORDiscretization::GetAssembledMatrix ( ) const
