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)
