Detailed Description

template<class D, class R, int dim>
class Dune::HierarchicalP2WithElementBubbleLocalFiniteElement< D, R, dim >

Linear Lagrange functions enriched with quadratic edge bubble functions and an element bubble function.

The set of basis functions contains the classical Lagrange basis functions of order 1, i.e., the barycentric coordinates, edge bubble functions as the product of two linear functions, and a single element bubble function that vanishes on all faces of the element. The element bubble function is the product of all linear basis functions and thus has polynomial order dim+1.

Note
The implementation here is restricted to simplex elements.
Template Parameters
DType to represent the field in the domain.
RType to represent the field in the range.
