Detailed Description

template<class Range, class Domain, class ES, template< class > class DerivativeTraits, size_t bufferSize>
class Dune::Functions::GridFunction< Range(Domain), ES, DerivativeTraits, bufferSize >

Wrapper class for functions defined on a Grid.

Being defined on a grid means in particular that you can evaluate the function in local coordinates of a given entities of the grid. The set of the entities this function is defined on is given by an EntitySet.

This models the Concept::GridFunction<Range(Domain), EntitySet, DerivativeTraits> concept.

Constructor & Destructor Documentation

GridFunction() [1/2]

template<class Range , class Domain , class ES , template< class > class DerivativeTraits, size_t bufferSize>

template<class F , disableCopyMove< GridFunction, F > = 0>

Dune::Functions::GridFunction< Range(Domain), ES, DerivativeTraits, bufferSize >::GridFunction ( F &&  f )

inline

Construct from function.

Template Parameters

F	Function type

Parameters

f	Function of type F

Requirements:

• The passed function f must be a module of the GridFunction concept, see Concept::GridFunction.

GridFunction() [2/2]

template<class Range , class Domain , class ES , template< class > class DerivativeTraits, size_t bufferSize>

Dune::Functions::GridFunction< Range(Domain), ES, DerivativeTraits, bufferSize >::GridFunction ( )

default

Member Function Documentation

entitySet()

template<class Range , class Domain , class ES , template< class > class DerivativeTraits, size_t bufferSize>

const EntitySet & Dune::Functions::GridFunction< Range(Domain), ES, DerivativeTraits, bufferSize >::entitySet ( ) const

inline

Get associated EntitySet.

The EntitySet is a range of grid entities the associated LocalFunction can be bound to.

operator()()

template<class Range , class Domain , class ES , template< class > class DerivativeTraits, size_t bufferSize>

Range Dune::Functions::GridFunction< Range(Domain), ES, DerivativeTraits, bufferSize >::operator() ( const Domain &  x ) const

inline

Evaluation of wrapped function.

Evaluate the wrapped function in global coordinates x.

Friends And Related Function Documentation

derivative

template<class Range , class Domain , class ES , template< class > class DerivativeTraits, size_t bufferSize>

DerivativeInterface derivative ( const GridFunction< Range(Domain), ES, DerivativeTraits, bufferSize > &  t )

friend

Get derivative of wrapped function.

This is a free function that will be found by ADL.

The derivative is returned as GridFunction of a type specified in the GridFunctionTraits.

localFunction

template<class Range , class Domain , class ES , template< class > class DerivativeTraits, size_t bufferSize>

LocalFunctionInterface localFunction ( const GridFunction< Range(Domain), ES, DerivativeTraits, bufferSize > &  t )

friend

Get local function of wrapped function.

This is a free function, to be found by ADL.

Notice that the returned LocalFunction can only be used after it has been bound to a proper local context.
