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]	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 >.

name()

template<class GridView >

virtual std::string Dune::VTKFunction< GridView >::name ( ) const

pure virtual

get name

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

precision()

template<class GridView >

virtual VTK::Precision Dune::VTKFunction< GridView >::precision ( ) const

inlinevirtual

get output precision for the field

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