Detailed Description

template<class FunctionSpace, class GridPart>
class Dune::ACFem::ZeroModel< FunctionSpace, GridPart >

Define a simple zero model to optimize expression templates.

Actually, this is only of very little use: the ModelInterface is only partly a \(L^\infty\) module, only partly a vector space, but nevertheless ModelExpression templates ease your live.

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.

forcesFunctional()

TraitsType::template ForcesFunctionalTraits< DiscreteFunctionSpace >::FunctionalType Dune::ACFem::DefaultModel< Expression >::forcesFunctional ( const DiscreteFunctionSpace &  space ) const

inlineinherited

Generate an instance of a class defining a functional which forms part of the force-terms for the model.

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.
