Constructor & Destructor Documentation

ConstGridFunction()

template<typename GV , typename RF , unsigned dimR = 1>

Dune::PDELab::ConstGridFunction< GV, RF, dimR >::ConstGridFunction ( const GV &  gv, const typename Traits::RangeType &  val_ = 1  )

inline

Contruct a Const GridFunction.

Parameters

gv	The GridView to use. It is passed as a reference to AnalyticGridFunctionBase (look there for the requirements of this argument).
val_	The value tu return on evaluation. This class stores a copy of that value.

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

inlineinherited

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]	e	The entity to evaluate on
[in]	x	The position in entity-local coordinates
[out]	y	The result of the evaluation

evaluateGlobal()

template<typename GV , typename RF , unsigned dimR = 1>

void Dune::PDELab::ConstGridFunction< GV, RF, dimR >::evaluateGlobal ( const typename Traits::DomainType &  x, typename Traits::RangeType &  y  ) const

inline

evaluate the function globally

Parameters

x	Position in global coordinates where to evaluate.
y	The resulting value.

getGridView()

template<typename T , typename Imp >

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

inlineinherited

setDataSetType()

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

inlineinherited

Set the data set type of this function.

setTime()

template<typename Time >

void Dune::PDELab::InstationaryFunctionDefaults::setTime ( Time  t )

inlineinherited

set time for subsequent evaluation

This method sets the time for subsequent calls to any of the evaluation methods.

Note

This default method does nothing, it just ensures setTime() can be called without ill effects.

Function implementation are free to restrict the types of acceptable parameters. This should be noted in the function classes documentation.
