Detailed Description

template<typename T, typename Imp>
class Dune::PDELab::AnalyticGridFunctionBase< T, Imp >

an analytic grid function

This is a convenience class which eases the creation of analytic GridFunctions. Classes derived from it need only implement a method evaluateGlobal(const Dune::FieldVector<typename Traits::DomainFieldType,GV::dimensionworld> &x_global, RangeType &y) to have a full-fledged GridFunction.

Template Parameters
TThe Traits class
ImpClass implementing the function. Imp must be derived from AnalyticGridFunctionBase in some way (Barton-Nackman-Trick).

Member Function Documentation

◆ evaluate()

template<typename T , typename Imp >
void Dune::PDELab::AnalyticGridFunctionBase< T, Imp >::evaluate ( const typename Traits::ElementType &  e,
const typename Traits::DomainType &  x,
typename Traits::RangeType &  y 
) const
inline

Evaluate the GridFunction at given position.

Evaluates components of the grid function at the given position and returns these values in a vector.

Parameters
[in]eThe entity to evaluate on
[in]xThe position in entity-local coordinates
[out]yThe result of the evaluation
