◆ evaluate()
template<class GridView >

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] comp number of component to be evaluated [in] e reference to grid entity of codimension 0 [in] xi point in local coordinates of the reference element of e
- Returns
- value of the component
Implemented in Dune::P1VTKFunction< GV, V >, and Dune::P0VTKFunction< GV, V >.
◆ ncomps()
template<class GridView >
|
pure virtual |
return number of components (1 for scalar valued functions, 3 for vector valued function in 3D etc.)
Implemented in Dune::P0VTKFunction< GV, V >, and Dune::P1VTKFunction< GV, V >.
