Detailed Description

template<class LocalFunction, std::size_t IndeterminateId = Policy::indeterminateId()>
class Dune::ACFem::GridFunction::LocalFunctionPlaceholder< LocalFunction, IndeterminateId >

A placeholder tensor which wraps a Dune::Fem LocalFunction.

Parameters

LocalFunction	The local function which provides the values.
IndeterminateId	The id of the indeterminate tensor the placeholder is assumed to depend on. The derivative method is overloaded such that the derivative w.r.t. to IndeterminateId will generate the placeholder tensor which takes its values from the jacobian() method of the wrapped LocalFunction.

Member Function Documentation

bind()

template<class LocalFunction , std::size_t IndeterminateId = Policy::indeterminateId()>

void Dune::ACFem::GridFunction::LocalFunctionPlaceholder< LocalFunction, IndeterminateId >::bind ( const EntityType &  entity )

inline

Bind the wrapped LocalFunction to the given entity.

Parameters

entity

The entity to bind to.

setValue()

template<class LocalFunction , std::size_t IndeterminateId = Policy::indeterminateId()>

template<class Point , std::enable_if_t<(IsQuadraturePoint< Point >::value||IsFieldVector< Point >::value), int > = 0>

void Dune::ACFem::GridFunction::LocalFunctionPlaceholder< LocalFunction, IndeterminateId >::setValue ( const Point &  point )

inline

Trigger the update of the stored values by evaluating the wrapped localfunction.

Calling setValue() without binding the wrapped LocalFunction to an entity by calling the bind() method may cause runtime errors.

Parameters

[in]

Point
