DG elements based on vector valued polynomials.
These elements use vector valued polynomial spaces as they have been introduced for Hdiv and Hcurl conforming finite elements, but do not use the usual continuity of these elements. Thus, they are suitable for DG and hybrid formulations involving these function spaces.
The template argument PolynomialType refers to a vector valued polynomial space like PolynomialsRaviartThomas or PolynomialsNedelec. Note that the dimension of the polynomial space and the argument dim must coincide.

| FE_DGVector< PolynomialType, dim, spacedim >::FE_DGVector | ( | const unsigned int | p, |
| MappingType | m | ||
| ) |
Constructor for the vector element of degree p.
|
overridevirtual |
Return a string that uniquely identifies a finite element. This class returns FE_RaviartThomas<dim>(degree), with dim and degree replaced by appropriate values.
Implements FiniteElement< dim, spacedim >.
Reimplemented in FE_DGBDM< dim, spacedim >, FE_DGRaviartThomas< dim, spacedim >, and FE_DGNedelec< dim, spacedim >.
|
overridevirtual |
A sort of virtual copy constructor, this function returns a copy of the finite element object. Derived classes need to override the function here in this base class and return an object of the same type as the derived class.
Some places in the library, for example the constructors of FESystem as well as the hp::FECollection class, need to make copies of finite elements without knowing their exact type. They do so through this function.
Implements FiniteElement< dim, spacedim >.
|
overridevirtual |
This function returns true, if the shape function shape_index has non-zero function values somewhere on the face face_index.
For this element, we always return true.
Reimplemented from FiniteElement< dim, spacedim >.
|
overridevirtual |
Determine an estimate for the memory consumption (in bytes) of this object.
This function is made virtual, since finite element objects are usually accessed through pointers to their base class, rather than the class itself.
Reimplemented from FiniteElement< dim, spacedim >.

staticprivate |
Only for internal use. Its full name is get_dofs_per_object_vector function and it creates the dofs_per_object vector that is needed within the constructor to be passed to the constructor of FiniteElementData.
