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

GV	GridView.
RF	The range field type of the Navier-Stokes solution.
F	Momentum source term function
B	Boundary condition function
V	Dirichlet velocity boundary condition function
J	Neumann 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 $J=p \cdot n$.
navier	Flag turning the local operator to a Navier-Stokes one.
full_tensor	Flag enabling the assembling of the full tensor of the viscous stress.
IP	A 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

And invocation in the code:

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

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
