Detailed Description

template<typename GV>
class Dune::Functions::RannacherTurekPreBasis< GV >

Pre-basis for a Rannacher-Turek basis.

These are Crouzeix-Raviart-elements for quadrilateral elements. See Rolf Rannacher and Stefan Turek. Simple nonconforming quadrilateral Stokes element. Numerical Methods for Partial Differential Equations, 8:97–111, 1992.

Template Parameters

GV	The grid view that the FE basis is defined on
