Detailed Description

template<class GridType, class RestProlOperatorImp>
class Dune::Fem::AdaptationManager< GridType, RestProlOperatorImp >

This class manages the adaptation process including a load balancing after the adaptation step. This class is created by the AdaptationManager for each grid instance. See AdaptationManager for details.

Constructor & Destructor Documentation

AdaptationManager() [1/2]

template<class GridType , class RestProlOperatorImp >

Dune::Fem::AdaptationManager< GridType, RestProlOperatorImp >::AdaptationManager ( GridType &  grid, RestProlOperatorImp &  rpOp, int  balanceCounter, const ParameterReader &  parameter = Parameter::container()  )

inline

constructor of AdaptationManager

The following optional parameters are used:

# 0 == none, 1 == generic, 2 == call back (only AlbertaGrid and ALUGrid)
fem.adaptation.method: 1 # default value
 
# balance every x-th call to adapt, 0 means no balancing
fem.loadbalancing.step: 1 # default value

Parameters

grid	Grid that adaptation is done for
rpOp	restriction and prlongation operator that describes how the user data is projected to other grid levels
balanceCounter	start counter for balance cycle (default = 0)
parameter	Parameter class holding parameters

References DUNE_THROW, and Dune::Fem::Parameter::verbose().

adapt()

template<class GridType , class RestProlOperatorImp >

virtual void Dune::Fem::AdaptationManager< GridType, RestProlOperatorImp >::adapt ( )

on call of this method the internal adaptation operator is called.

Reimplemented from Dune::Fem::AdaptationManagerBase< GridType, RestProlOperatorImp >.

adaptationTime()

template<class GridType , class RestProlOperatorImp >

virtual double Dune::Fem::AdaptationManagerBase< GridType, RestProlOperatorImp >::adaptationTime ( ) const

inlinevirtualinherited

time that last adaptation cycle took

Reimplemented from Dune::Fem::AdaptationManagerInterface.

adaptive()

template<class GridType >

virtual bool Dune::Fem::AdaptationMethod< GridType >::adaptive ( ) const

inlinevirtualinherited

returns true if adaptation manager as adaptation method different to NONE

Returns

true if adaptation method is not NONE, false otherwise

Reimplemented from Dune::Fem::AdaptationManagerInterface.

References Dune::Fem::AdaptationMethod< GridType >::adaptationMethod_, and Dune::Fem::AdaptationMethod< GridType >::none.

getRestProlOp()

template<class GridType , class RestProlOperatorImp >

RestProlOperatorImp & Dune::Fem::AdaptationManagerBase< GridType, RestProlOperatorImp >::getRestProlOp ( )

inlineinherited

no public method, but has to be public, because all AdaptationManagers must be able to call this method and the template parameters are allways different

isCallBackAdaptation()

template<class GridType >

virtual bool Dune::Fem::AdaptationMethod< GridType >::isCallBackAdaptation ( ) const

inlinevirtualinherited

return true if callback adaptation is used.

Reimplemented from Dune::Fem::AdaptationManagerInterface.

References Dune::Fem::AdaptationMethod< GridType >::adaptationMethod_, and Dune::Fem::AdaptationMethod< GridType >::callback.

loadBalance()

template<class GridType , class RestProlOperatorImp >

virtual bool Dune::Fem::AdaptationManager< GridType, RestProlOperatorImp >::loadBalance ( )

inlinevirtual

call load balance, returns true if grid was changed

Returns

true if grid was changed, false otherwise

Reimplemented from Dune::Fem::AdaptationManagerBase< GridType, RestProlOperatorImp >.

loadBalanceTime()

template<class GridType , class RestProlOperatorImp >

virtual double Dune::Fem::AdaptationManager< GridType, RestProlOperatorImp >::loadBalanceTime ( ) const

inlinevirtual

time that last load balance cycle took

Reimplemented from Dune::Fem::LoadBalancer< GridType >.

methodName()

template<class GridType >

virtual const char * Dune::Fem::AdaptationMethod< GridType >::methodName ( ) const

inlinevirtualinherited

returns name of adaptation method

Returns

name of adaptation method

Reimplemented from Dune::Fem::AdaptationManagerInterface.

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
