Forward some basic type from the supplied function-spaces to the model class. Note that FunctionSpace is defined as a shortcut for RangeFunctionSpace in order to simplify the common case DomainFunctionSpace == RangeFunctionSpace.

Detailed Description

template<class FunctionSpace>
class Dune::ACFem::PDEModel::FluidSelfTransportModel< FunctionSpace >

Define a model for the "Navier-Stokes" non-lineariry.

An alternate formulation of the the Navier-Stokes non-linearity obtained by integration by parts, at the cost of introducting a boundary integral for non-Dirichlet boundaries

In formulas: this fragment implements the right-hand-side of the following equation (where the equality only holds for \(\nabla\cdot U = 0\)):

\[ \int_\Omega U_i\,\partial_i U_j\,\phi_j = - \int_\Omega U_i\,U_j\,\partial_i\phi_j + \int_{\partial\Omega} U\cdot\nu\,U\cdot\phi \]

Of course, the formula uses sum-convention. The left-hand-side is implemented by IncompressibleSelfTransportModel.

Parameters

GridPart

The grid-part we live on.

Member Function Documentation

bind()

void Dune::ACFem::ModelBase< FunctionSpace , FunctionSpace >::bind ( const Entity &  entity )

inlineinherited

Bind to the given entity.

Parameters

[in]

entity

The entity to bind to.

Warning

Calling any other method without first binding the model results in undefined behaviour.

Models needing this method need to reimplement it. This is just here to obey the "bindable" interface of Dune::Fem.

unbind()

void Dune::ACFem::ModelBase< FunctionSpace , FunctionSpace >::unbind ( )

inlineinherited

Unbind from the previously bound entity.

Warning

Calling this method on an unbound model may cause undefined behaviour.

Models needing this method need to reimplement it. This is just here to obey the "bindable" interface of Dune::Fem.
