Detailed Description

template<class D, class R, int dim>
class Dune::RefinedP0LocalBasis< D, R, dim >

Uniformly refined constant shape functions on a unit simplex in R^dim.

This shape function set mimicks the P0 shape functions that you would get on a uniformly refined grid. Hence these shape functions are only piecewise constant!

Shape functions like these are necessary for hierarchical error estimators for certain nonlinear problems.

The functions are associated with the subelements as defined in RefinedSimplexLocalBasis

Template Parameters

D	Type to represent the field in the domain.
R	Type to represent the field in the range.
dim	Dimension of domain space

Doesn't really apply: these shape functions are only piecewise constant
