◆ evaluate()

template<class GridView >
virtual double Dune::VTKFunction< GridView >::evaluate ( int  comp,
const Entity &  e,
const Dune::FieldVector< ctype, dim > &  xi 
) const
pure virtual

evaluate single component comp in the entity e at local coordinates xi

Evaluate the function in an entity at local coordinates.

Parameters
[in]compnumber of component to be evaluated
[in]ereference to grid entity of codimension 0
[in]xipoint in local coordinates of the reference element of e
Returns
value of the component

Implemented in Dune::P0VTKFunction< GV, V >, and Dune::P1VTKFunction< GV, V >.

◆ ncomps()

template<class GridView >
virtual int Dune::VTKFunction< GridView >::ncomps ( ) const
pure virtual

return number of components (1 for scalar valued functions, 3 for vector valued function in 3D etc.)

Implemented in Dune::P1VTKFunction< GV, V >, and Dune::P0VTKFunction< GV, V >.
