Detailed Description

Class bundling a hierarchy finite element spaces together with the corresponding prolongation operators

Definition at line 26 of file fespacehierarchy.hpp.

Constructor & Destructor Documentation

mfem::FiniteElementSpaceHierarchy::FiniteElementSpaceHierarchy	(	Mesh *	mesh,
		FiniteElementSpace *	fespace,
		bool	ownM,
		bool	ownFES
	)

Constructs a space hierarchy with the given mesh and space on the coarsest level.

The ownership of the mesh and space may be transferred to the FiniteElementSpaceHierarchy by setting the according boolean variables.

Definition at line 18 of file fespacehierarchy.cpp.

mfem::FiniteElementSpaceHierarchy::~FiniteElementSpaceHierarchy ( )

virtual

Destructor deleting all meshes and spaces that are owned.

Definition at line 28 of file fespacehierarchy.cpp.
