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 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 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)
