Dune::DiscreteCoordFunctionInterface< ct, dimR, Impl > Class Template Reference

Interface class for using a discrete function to define the geometry of a Dune::GeometryGrid. An implementation should be derived from Dune::DiscreteCoordinateFunction and the evaluate method taking an entity of the host grid together with the number of a vertex returns the coordinate in \( R^r \) of that corner. The user must ensure continuity of this mapping. In addition an adapt method is provided which is called whenever adapt() is called on the Dune::GeometryGrid. More...

Detailed Description

template<class ct, unsigned int dimR, class Impl>
class Dune::DiscreteCoordFunctionInterface< ct, dimR, Impl >

Interface class for using a discrete function to define the geometry of a Dune::GeometryGrid. An implementation should be derived from Dune::DiscreteCoordinateFunction and the evaluate method taking an entity of the host grid together with the number of a vertex returns the coordinate in \( R^r \) of that corner. The user must ensure continuity of this mapping. In addition an adapt method is provided which is called whenever adapt() is called on the Dune::GeometryGrid.

Template Parameters

ct	coordinate field type (ct in Dune::GeometryGrid)
dimR	dimension of the range of the mapping (dimensionworld in Dune::GeometryGrid)
Impl	implementation class (BN trick)

template<class HostEntity >

void Dune::DiscreteCoordFunctionInterface< ct, dimR, Impl >::evaluate ( const HostEntity &  hostEntity, unsigned int  corner, RangeVector &  y  ) const

inline

evaluate method

Parameters

hostEntity	an entity of the host grid
corner	the local number of the corner in the host entity
y	return value for the coordinate of this corner

Note

This method needs to work for entities of all codimensions, not just for elements!
