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

T	The Traits class
Imp	Class implementing the function. Imp must be derived from AnalyticGridFunctionBase in some way (Barton-Nackman-Trick).

Constructor & Destructor Documentation

AnalyticGridFunctionBase()

template<typename T , typename Imp >

Dune::PDELab::AnalyticGridFunctionBase< T, Imp >::AnalyticGridFunctionBase ( const typename Traits::GridViewType &  g_ )

Member Function Documentation

dataSetType()

Output::DataSetType Dune::PDELab::GridFunctionOutputParameters::dataSetType ( ) const

inlineinherited

Return the data set type of this function.

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

inline

setDataSetType()

void Dune::PDELab::GridFunctionOutputParameters::setDataSetType ( Output::DataSetType  dataSetType )

inlineinherited

Set the data set type of this function.
