Detailed Description

template<typename GV, typename RF, typename F, typename B, typename V, typename J, bool navier = false, bool full_tensor = false, typename IP = DefaultInteriorPenalty<typename V::Traits::RangeFieldType>>
class Dune::PDELab::DGNavierStokesParameters< GV, RF, F, B, V, J, navier, full_tensor, IP >

Parameter class for local operator DGNavierStokes.

Template Parameters
GVGridView.
RFThe range field type of the Navier-Stokes solution.
FMomentum source term function
BBoundary condition function
VDirichlet velocity boundary condition function
JNeumann stress boundary function (vector- or scalar-valued). Scalar values will be interpreted as the magnitude of a vector oriented in outer normal direction. For prescribed pressure you can use $J=p \cdot n$.
navierFlag turning the local operator to a Navier-Stokes one.
full_tensorFlag enabling the assembling of the full tensor of the viscous stress.
IPA class providing the interior penalty for each face.

Constructor & Destructor Documentation

◆ DGNavierStokesParameters()

template<typename GV , typename RF , typename F , typename B , typename V , typename J , bool navier = false, bool full_tensor = false, typename IP = DefaultInteriorPenalty<typename V::Traits::RangeFieldType>>
Dune::PDELab::DGNavierStokesParameters< GV, RF, F, B, V, J, navier, full_tensor, IP >::DGNavierStokesParameters ( const Dune::ParameterTree configuration,
F &  f,
B &  b,
V &  v,
J &  j 
)
inline

Constructor that parses values from parameter tree.

In order to parse the values correctly the ini-file should have the following structure:

[parameters]
rho = 1.0
mu = 1.0
[parameters.dg]
epsilon = -1
sigma = 6.0
beta = 1.0
Traits::RangeField rho(const EG &eg, const typename Traits::Domain &x) const
Density value from local cell coordinate.
Definition: stokesparameter.hh:221
Traits::RangeField mu(const EG &e, const typename Traits::Domain &x) const
Dynamic viscosity value from local cell coordinate.
Definition: stokesparameter.hh:205

And invocation in the code:

navierstokes_parameters(configuration.sub("parameters"), ... );

Member Function Documentation

◆ epsilonIPSymmetryFactor()

template<typename GV , typename RF , typename F , typename B , typename V , typename J , bool navier = false, bool full_tensor = false, typename IP = DefaultInteriorPenalty<typename V::Traits::RangeFieldType>>
int Dune::PDELab::DGNavierStokesParameters< GV, RF, F, B, V, J, navier, full_tensor, IP >::epsilonIPSymmetryFactor ( )
inline

Return the symmetry factor epsilon for this IP discretization
