Constructor & Destructor Documentation

mfem::ParLORDiscretization::ParLORDiscretization ( ParBilinearForm 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 ParMesh::MakeRefined).

Definition at line 410 of file lor.cpp.

mfem::ParLORDiscretization::ParLORDiscretization ( ParFiniteElementSpace fes_ho,
int  ref_type = BasisType::GaussLobatto 
)

Construct a low-order refined version of the ParFiniteElementSpace pfes_ho.

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