BlockDiagonalLinearOperator.

Member Function Documentation

beginAssemble()

void Dune::Fem::AssembledOperator< AdaptiveDiscreteFunction< DiscreteFunctionSpace > , AdaptiveDiscreteFunction< DiscreteFunctionSpace > >::beginAssemble ( )

inlineinherited

Initiate the assemble of values using the LocalContribution concept.

Template Parameters

AssembleOperation

the specific operation (Add, Set, ...)

communicate()

template<class DiscreteFunctionSpace , class LocalBlock = Dune::FieldMatrix< typename DiscreteFunctionSpace :: RangeFieldType, DiscreteFunctionSpace::localBlockSize, DiscreteFunctionSpace::localBlockSize >>

void Dune::Fem::BlockDiagonalLinearOperator< DiscreteFunctionSpace, LocalBlock >::communicate ( )

inline

copy matrices to ghost cells to make this class work in parallel

Note

needs the block methods to behave like discrete function (needed to make this class work with CommunicationManager)

endAssemble()

void Dune::Fem::AssembledOperator< AdaptiveDiscreteFunction< DiscreteFunctionSpace > , AdaptiveDiscreteFunction< DiscreteFunctionSpace > >::endAssemble ( )

inlineinherited

Finalize the assemble of values using the LocalContribution concept.

Template Parameters

AssembleOperation

the specific operation (Add, Set, ...)

finalize()

virtual void Dune::Fem::Operator< AdaptiveDiscreteFunction< DiscreteFunctionSpace > , AdaptiveDiscreteFunction< DiscreteFunctionSpace > >::finalize ( )

inlinevirtualinherited

finalization of operator

Note

The default implementation is empty.

nonlinear()

virtual bool Dune::Fem::LinearOperator< AdaptiveDiscreteFunction< DiscreteFunctionSpace > , AdaptiveDiscreteFunction< DiscreteFunctionSpace > >::nonlinear ( ) const

inlinevirtualinherited

Return true if the Operator is nonlinear and false otherwise (default is true).

Reimplemented from Dune::Fem::Operator< AdaptiveDiscreteFunction< DiscreteFunctionSpace >, AdaptiveDiscreteFunction< DiscreteFunctionSpace > >.

operator()()

virtual void Dune::Fem::Operator< AdaptiveDiscreteFunction< DiscreteFunctionSpace > , AdaptiveDiscreteFunction< DiscreteFunctionSpace > >::operator() ( const DomainFunctionType &  u, RangeFunctionType &  w  ) const

pure virtualinherited

application operator

Parameters

[in]	u	argument discrete function
[out]	w	destination discrete function

Note

This method has to be implemented by all derived classes.

positiveDefinite()

virtual bool Dune::Fem::LinearOperator< AdaptiveDiscreteFunction< DiscreteFunctionSpace > , AdaptiveDiscreteFunction< DiscreteFunctionSpace > >::positiveDefinite ( ) const

inlinevirtualinherited

Return true if the Operator is positive definite.

symmetric()

virtual bool Dune::Fem::LinearOperator< AdaptiveDiscreteFunction< DiscreteFunctionSpace > , AdaptiveDiscreteFunction< DiscreteFunctionSpace > >::symmetric ( ) const

inlinevirtualinherited

Return true if the Operator is symmetric.
