Detailed Description

template<class GV, class R>
class Dune::Functions::BSplineLocalFiniteElement< GV, R >

LocalFiniteElement in the sense of dune-localfunctions, for the B-spline basis on tensor-product grids.

This class ties together the implementation classes BSplineLocalBasis, BSplineLocalCoefficients, and BSplineLocalInterpolation

Template Parameters
DNumber type used for domain coordinates
RNumber type used for spline function values

◆ bind()

template<class GV , class R >
void Dune::Functions::BSplineLocalFiniteElement< GV, R >::bind ( const std::array< unsigned, dim > &  elementIdx)
inline

Bind LocalFiniteElement to a specific knot span of the spline patch.

Elements are the non-empty knot spans, here we do the renumbering

Parameters
ijkInteger coordinates in the tensor product patch
