mfem::RT_FECollection::RT_FECollection ( const int  p,
const int  dim,
const int  cb_type = BasisType::GaussLobatto,
const int  ob_type = BasisType::GaussLegendre 
)

Construct an H(div)-conforming Raviart-Thomas FE collection, RT_p.

The index p corresponds to the space RT_p, as typically denoted in the literature, which contains vector polynomials of degree up to (p+1). For example, the RT_0 collection contains vector-valued linear functions and, in particular, FiniteElementCollection::GetOrder() will, correspondingly, return order 1.

Member Function Documentation

◆ Clone()

FiniteElementCollection* mfem::RT_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 425 of file fe_coll.hpp.

◆ DofForGeometry()

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

Implements mfem::FiniteElementCollection.

Definition at line 414 of file fe_coll.hpp.

◆ DofOrderForOrientation()

const int * mfem::RT_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.
