Member Function Documentation

◆ Clone()

FiniteElementCollection * mfem::L2_FECollection::Clone ( int p ) const

inlineoverridevirtual

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 375 of file fe_coll.hpp.

◆ DofForGeometry()

int mfem::L2_FECollection::DofForGeometry ( Geometry::Type GeomType ) const

inlineoverridevirtual

Implements mfem::FiniteElementCollection.

Definition at line 351 of file fe_coll.hpp.

◆ DofOrderForOrientation()

const int * mfem::L2_FECollection::DofOrderForOrientation	(	Geometry::Type	GeomType,
		int	Or ) const

overridevirtual

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.
