Define the RHS functional.

The default for forces and Neumann is a ZeroGridFunction which will result in a ZeroFunctional which simply will do nothing.

For assembling, both will be added efficently together using FunctionalExpressions.

Detailed Description

template<class DiscreteFunction, class ImplicitModel, class ExplicitDataFunction, class ExplicitModel>
class Dune::ACFem::SplittingFemScheme< DiscreteFunction, ImplicitModel, ExplicitDataFunction, ExplicitModel, ZeroGridFunction< typename ImplicitModel::FunctionSpaceType, typename ImplicitModel::GridPartType > >

Constructor.

Parameters
[in,out]solutionStorage for the discrete solution.
[in]implicitModelThe part of the operator to be applied at the end of the time interval.
[in]explicitDataThe grid-function the operator defined by explicitModel is applied to. This defaults to the ZeroGridFunction.
[in]explicitModelThe part of the operator to be applied to the old values. This defaults to the ZeroModel.
[in]initialGuessInitial guess. If present, initialize() will call the natural interpolation routine for the given discrete function space.
[in]nameName used for parameters and output.

Member Typedef Documentation

◆ ExplicitOperatorType

typedef EllipticOperator<ExplicitModelType, ExplicitDataFunctionType, DiscreteFunctionType, EmptyConstraintsType> Dune::ACFem::SplittingFemSchemeBase< DiscreteFunction, ImplicitModel, ExplicitDataFunction, ExplicitModel, ZeroGridFunction< ImplicitModel::FunctionSpaceType, ImplicitModel::GridPartType > >::ExplicitOperatorType
inherited

explicit part of differential operator.

Need not be differentiable as it is only needed for the RHS.

◆ RestrictionProlongationType

typedef Dune::Fem::RestrictProlongDefault<DiscreteFunctionType> Dune::ACFem::SplittingFemSchemeBase< DiscreteFunction, ImplicitModel, ExplicitDataFunction, ExplicitModel, ZeroGridFunction< ImplicitModel::FunctionSpaceType, ImplicitModel::GridPartType > >::RestrictionProlongationType
inherited

type of restriction/prolongation projection for adaptive simulations (use default here, i.e.

LagrangeInterpolation)

◆ error()

virtual double Dune::ACFem::SplittingFemSchemeBase< DiscreteFunction, ImplicitModel, ExplicitDataFunction, ExplicitModel, ZeroGridFunction< ImplicitModel::FunctionSpaceType, ImplicitModel::GridPartType > >::error ( ) const
inlinevirtualinherited

Calculate L2/H1 error.

This actually computes the distance to the initial value which optionally may be used for experimental convergence tests in order to pass an exact "solution". In this case initialGuess may be time-dependent and has to give the correct value at the start of the time-step.

Implements Dune::ACFem::BasicFemScheme.

◆ linearSolve()

virtual void Dune::ACFem::SplittingFemSchemeBase< DiscreteFunction, ImplicitModel, ExplicitDataFunction, ExplicitModel, ZeroGridFunction< ImplicitModel::FunctionSpaceType, ImplicitModel::GridPartType > >::linearSolve ( DiscreteFunctionType rhs,
bool  forceMatrixAssembling 
)
inlineprotectedvirtualinherited

Perform only one step of the Newton scheme for the affine-linear case.

This implies that an affine linear case is really allowed.
