Implementation of scalar, discontinuous tensor product elements based on Legendre polynomials, described by the tensor product of the polynomial space Polynomials::Legendre. As opposed to the basic FE_DGQ element, these elements are not interpolatory and no support points are defined.
See the base class documentation in FE_DGQ for details.
| FE_DGQLegendre< dim, spacedim >::FE_DGQLegendre | ( | const unsigned int | degree | ) |
Constructor for tensor product polynomials based on Polynomials::Legendre interpolation.
|
overridevirtual |
Return a list of constant modes of the element. For the Legendre basis, it returns one row where the first element (corresponding to the constant mode) is set to true and all other elements are set to false.
Reimplemented from FE_DGQ< dim, spacedim >.
|
overridevirtual |
Return a string that uniquely identifies a finite element. This class returns FE_DGQLegendre<dim>(degree) with dim and degree replaced by the values given by the template parameter and the argument passed to the constructor, respectively.
Reimplemented from FE_DGQ< 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.
Reimplemented from FE_DGQ< dim, spacedim >.
