Member Function Documentation

◆ Clone()

FiniteElementCollection* mfem::H1_FECollection::Clone ( int  p) const
inlinevirtual

Instantiate a new collection of the same type with a different order.

Generally, the order parameter p is NOT the same as the parameter p used by some of the constructors of derived classes. Instead, this p represents the order of the new FE collection as it will be returned by its GetOrder() method.

Reimplemented from mfem::FiniteElementCollection.

Definition at line 291 of file fe_coll.hpp.

◆ DofForGeometry()

virtual int mfem::H1_FECollection::DofForGeometry ( Geometry::Type  GeomType) const
inlinevirtual

Implements mfem::FiniteElementCollection.

Definition at line 275 of file fe_coll.hpp.

◆ DofOrderForOrientation()

const int * mfem::H1_FECollection::DofOrderForOrientation ( Geometry::Type  GeomType,
int  Or 
) const
virtual

Returns an array, say p, that maps a local permuted index i to a local base index: base_i = p[i].

Note
Only provides information about interior dofs. See FiniteElementCollection::SubDofOrder if interior and boundary dof order is needed.

Implements mfem::FiniteElementCollection.

Definition at line 1966 of file fe_coll.cpp.

const int * mfem::H1_FECollection::GetDofMap ( Geometry::Type  GeomType) const

◆ GetDofMap() [2/2]

const int * mfem::H1_FECollection::GetDofMap ( Geometry::Type  GeomType,
