Detailed Description

template<class A, class B>
class Dune::Fem::CombinedLocalOperator< A, B >

This operator combines two local operator in the following way:

$$Op(a,d) = (A + B)(a,d)$$

whereby B is first applied and then A. The operators A and B have to be defined such that they localy add thier results to a given destination. This workaround can be used directly but the normal way should be to define two discrete operators and then add them which uses intern this class two add the local operators. OP(a,d) = (A + B)(a,d) Note: first B is evaluated, then A

Member Function Documentation

applyLocal()

template<class A , class B >

template<class EntityType >

void Dune::Fem::CombinedLocalOperator< A, B >::applyLocal ( EntityType &  en )

inline

applyLocal defines the action one might do on a given or on two given entities. Up to now only max two entities may be parameter but this can be advanced. There is also an applyLocal method with no entity which means that also operators which dont need a grid walktrough can be combined.

finalizeLocal() [1/2]

template<class A , class B >

template<class EntityType >

void Dune::Fem::CombinedLocalOperator< A, B >::finalizeLocal ( EntityType &  en )

inline

Todo:

Please doc me!

finalizeLocal() [2/2]

template<class A , class B >

template<class EntityType >

void Dune::Fem::CombinedLocalOperator< A, B >::finalizeLocal ( EntityType &  en1, EntityType &  en2  )

inline

Todo:

Please doc me!

prepareGlobal()

template<class A , class B >

template<class FirstParamType , class SecondParamType >

void Dune::Fem::CombinedLocalOperator< A, B >::prepareGlobal ( const FirstParamType &  pa, SecondParamType &  pb  )

inline

prepareGlobal is called before the grid walktrough

the parameters of prepareGlobal and finalizeGlobal are set outside via a setParameter method or something

prepareLocal()

template<class A , class B >

template<class EntityType >

void Dune::Fem::CombinedLocalOperator< A, B >::prepareLocal ( EntityType &  en )

inline

prepareLocal is called before applyLocal is called, it has different length of parameter list, which are always entities. For example one might give no parameters to prepareLocal or father and son element, depends on grid walktrough outside

saveObjPointer()

template<class DiscrOpType , class LocalOpType >

void Dune::Fem::ObjPointerStorage::saveObjPointer ( DiscrOpType *  discrOp, LocalOpType *  lop  )

inlineinherited

Store new generated DiscreteOperator Pointer and the LocalOperator pointer
