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