Detailed Description

template<class LinearFunctional>
struct Dune::ACFem::ForcesFunctionalModel< LinearFunctional >

Wrap an existing DiscreteLinearFunctional into a model which only conatains this ModelConstituent.

The most convenient way to add a DiscreteLinearFunctional to the "right-hande-side" of a model is the use of algebraic expressions:

MyFunctionalObject Phi;
auto newModel = existingModel - Phi;

The underlying expression-templates will form a suitable ForcesFunctionalModel by means of the overloaded operator-() function and add that to the existing model.

Member Function Documentation

bulkForcesFunction()

BulkForcesFunctionType Dune::ACFem::DefaultModel< Expression >::bulkForcesFunction ( const GridPartType &  gridPart ) const

inlineinherited

Generate an instance of a class defining the bulk-forces the model is subject to.

The return object is a Fem grid-function. This can be used for the case where the "right hand side" is an L2-function.

dirichletBoundaryFunction()

DirichletBoundaryFunctionType Dune::ACFem::DefaultModel< Expression >::dirichletBoundaryFunction ( const GridPartType &  gridPart ) const

inlineinherited

Generate an instance of a class defining Dirichlet boundary values as a Fem grid-function.

dirichletIndicator()

DirichletIndicatorType Dune::ACFem::DefaultModel< Expression >::dirichletIndicator ( ) const

inlineinherited

Generate an object to identify parts of the boundary subject to Dirichlet boundary conditions.

The return value has to obey the BoundaryIndicatorInterface.

dirichletWeightFunction()

DirichletWeightFunctionType Dune::ACFem::DefaultModel< Expression >::dirichletWeightFunction ( const GridPartType &  gridPart ) const

inlineinherited

Generate an instance of a class defining a "left hand side" weight on the Dirichlet boundary conditions, DefaultModelTraits::DirichletWeightFunctionType.

neumannBoundaryFunction()

NeumannBoundaryFunctionType Dune::ACFem::DefaultModel< Expression >::neumannBoundaryFunction ( const GridPartType &  gridPart ) const

inlineinherited

Generate an instance of a class defining Neumann boundary values as a Fem grid-function.

neumannIndicator()

NeumannIndicatorType Dune::ACFem::DefaultModel< Expression >::neumannIndicator ( ) const

inlineinherited

Generate an object to identify parts of the boundary subject to Neumann boundary conditions.

The return value has to obey the BoundaryIndicatorInterface.
