Detailed Description

template<int dim>
class Dune::HierarchicalSimplexP2WithElementBubbleLocalCoefficients< dim >

The local finite element needed for the Zou-Kornhuber estimator for Signorini problems.

This shape function set consists of three parts:

• Linear shape functions associated to the element vertices
• Piecewise linear edge bubbles
• A cubic element bubble

Currently this element exists only for triangles!

The functions are associated to points by:

f_0 ~ (0.0, 0.0) f_1 ~ (1.0, 0.0) f_2 ~ (0.0, 1.0) f_3 ~ (0.5, 0.0) f_4 ~ (0.0, 0.5) f_5 ~ (0.5, 0.5) f_6 ~ (1/3, 1/3)

Template Parameters

D	Type to represent the field in the domain.
R	Type to represent the field in the range.
