Detailed Description

class FEType hides (possibly multiple) FEFamily and approximation orders, thereby enabling specialized finite element families.

Definition at line 43 of file fe_type.h.

Constructor & Destructor Documentation

libMesh::FEType::FEType ( const Order  o = FIRST,
const FEFamily  f = LAGRANGE 
) [inline]

Constructor. Optionally takes the approximation Order and the finite element family FEFamily

Definition at line 53 of file fe_type.h.

                                      :
    order(o),
    family(f)
  {}
libMesh::FEType::FEType ( const Order  o = FIRST,
const FEFamily  f = LAGRANGE,
const Order  ro = THIRD,
const FEFamily  rf = JACOBI_20_00,
const InfMapType  im = CARTESIAN 
) [inline]

Constructor. Optionally takes the approximation Order and the finite element family FEFamily. Note that for non-infinite elements the order and base order are the same, as with the family and base_family. It must be so, otherwise what we switch on would change when infinite elements are not compiled in.

Order libMesh::FEType::default_quadrature_order ( ) const [inline]
Returns:
the default quadrature order for this FEType. The default quadrature order is calculated assuming a polynomial of degree order and is based on integrating the mass matrix for such an element exactly.

UniquePtr< QBase > libMesh::FEType::default_quadrature_rule ( const unsigned int  dim,
const int  extraorder = 0 
) const
Returns:
a quadrature rule of appropriate type and order for this FEType. The default quadrature rule is based on integrating the mass matrix for such an element exactly. Higher or lower degree rules can be chosen by changing the extraorder parameter.
