Member Function Documentation

applyLimiter()

virtual void Dune::Fem::SpaceOperatorInterface< OperatorType::DestinationType , Fem::AutomaticDifferenceOperator< OperatorType::DestinationType > >::applyLimiter ( DestinationType &  U ) const

inlinevirtualinherited

limiter application operator

Parameters

[in,out]

U

argument and destination to apply Limiter(u), needs internal copying

Note

: Default implementation is to do nothing (hasLimiter == false)

finalize()

virtual void Dune::Fem::Operator< JacobianOperator::DomainFunctionType , JacobianOperator::RangeFunctionType >::finalize ( )

inlinevirtualinherited

finalization of operator

Note

The default implementation is empty.

hasLimiter()

virtual bool Dune::Fem::SpaceOperatorInterface< OperatorType::DestinationType , Fem::AutomaticDifferenceOperator< OperatorType::DestinationType > >::hasLimiter ( ) const

inlinevirtualinherited

return true if limit method is implemented

Returns

true if limit is implemented

initializeTimeStepSize()

void Dune::Fem::SpaceOperatorInterface< OperatorType::DestinationType , Fem::AutomaticDifferenceOperator< OperatorType::DestinationType > >::initializeTimeStepSize ( const DestinationType &  U0 ) const

inlinevirtualinherited

call operator once to calculate initial time step size

Parameters

U0	initial data to compute initial time step size

jacobian()

virtual void Dune::Fem::DifferentiableOperator< AutomaticDifferenceLinearOperator< OperatorType::DestinationType, OperatorType::DestinationType > >::jacobian ( const DomainFunctionType &  u, JacobianOperatorType &  jOp  ) const

pure virtualinherited

obtain linearization

Parameters

[in]	u	argument discrete function
[out]	jOp	destination Jacobian operator

Note

This method has to be implemented by all derived classes.

limit()

virtual void Dune::Fem::SpaceOperatorInterface< OperatorType::DestinationType , Fem::AutomaticDifferenceOperator< OperatorType::DestinationType > >::limit ( const DestinationType &  arg, DestinationType &  dest  ) const

inlinevirtualinherited

limiter application operator

Parameters

arg	argument, u
dest	destination, Limiter(u)

Note

: Default implementation is to copy arg into dest.

nonlinear()

virtual bool Dune::Fem::Operator< JacobianOperator::DomainFunctionType , JacobianOperator::RangeFunctionType >::nonlinear ( ) const

inlinevirtualinherited

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

operator()()

virtual void Dune::Fem::Operator< JacobianOperator::DomainFunctionType , JacobianOperator::RangeFunctionType >::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.

Implemented in EllipticOperator< JacobianOperator::DomainFunctionType, JacobianOperator::RangeFunctionType, Model >.

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

References Dune::Fem::ObjPointerStorage::saveObjPointer().

setTime()

template<class OperatorType >

void Dune::Fem::SpaceOperatorPtr< OperatorType >::setTime ( const double  time )

inlinevirtualinherited

set time for operators

Parameters

time	current time of evaluation

Reimplemented from Dune::Fem::SpaceOperatorInterface< OperatorType::DestinationType >.

References Dune::Fem::SpaceOperatorStorage< OperatorType >::pass().

timeStepEstimate()

template<class OperatorType >

double Dune::Fem::SpaceOperatorPtr< OperatorType >::timeStepEstimate ( ) const

inlinevirtualinherited

estimate maximum time step

For an explicit time discretization, the time step has to be limited. An estimate for the maximum time step of an explicit Euler scheme is returned by this function. Maximum time steps for higher order Runge Kutta schemes can be derived from this value.

Reimplemented from Dune::Fem::SpaceOperatorInterface< OperatorType::DestinationType >.

References Dune::Fem::SpaceOperatorStorage< OperatorType >::pass().
