Detailed Description

template<class GridFunction, class Indicator = EntireBoundaryIndicatorType>
class Dune::ACFem::DirichletBoundaryModel< GridFunction, Indicator >

A Dirichlet model.

Form a Dirichlet-boundary-value model from an existing grid-function and a suitable BoundaryIndicator.

Parameters

[in]	GridFunction	The "right hand side" for the Dirichlet boundary conditions.
[in]	Indicator	The boundary indicator function which decides on which part of the boundary the Dirichlet data is imposed.

Note

GridFunction may already be a BoundarySupportedFunction in which case the resulting Dirichlet condition is imposed on the intersection of the supports of GridFunction and Indicator.

Bug:

ATM, the product of Indicator and GridFunction (which may already be a BoundarySupportedFunction) determine the part of the bounday subject to Dirichlet-conditions. This should perhaps be changed s.t. that only Indicator carries this information.

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.

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.
