default

◆ ParFiniteElementSpaceHierarchy() [2/2]

mfem::ParFiniteElementSpaceHierarchy::ParFiniteElementSpaceHierarchy ( ParMesh * mesh,
ParFiniteElementSpace * fespace,
bool ownM,
bool ownFES )

Constructs a parallel space hierarchy with the given mesh and spaces on level zero.

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