Detailed Description

template<typename HyperbolicDescription, int dim, typename Number = double>
class ryujin::InitialState< HyperbolicDescription, dim, Number >

A small abstract base class to group configuration options for a number of initial flow configurations.

Note

By convention all initial state configurations described by this class shall be centered at the origin (0, 0) and facing in positive x direction. The InitialValues wrapper class already allows to apply an affine translation to the coordinate system; so additional configuration options for location and direction are not needed.

InitialState()

template<typename HyperbolicDescription , int dim, typename Number = double>

ryujin::InitialState< HyperbolicDescription, dim, Number >::InitialState ( const std::string &  name, const std::string &  subsection  )

inline

Constructor taking initial state name name and a subsection subsection as an argument. The dealii::ParameterAcceptor is initialized with the subsubsection subsection + "/" + name.

Member Function Documentation

compute()

template<typename HyperbolicDescription , int dim, typename Number = double>

virtual state_type ryujin::InitialState< HyperbolicDescription, dim, Number >::compute ( const dealii::Point< dim > &  point, Number  t  )

pure virtual

Given a position point returns the corresponding (conserved) initial state. The function is used to interpolate initial values and enforce Dirichlet boundary conditions. For the latter, the function signature has an additional parameter t denoting the current time to allow for time-dependent (in-flow) Dirichlet data.

initial_precomputations()

template<typename HyperbolicDescription , int dim, typename Number = double>

virtual initial_precomputed_type ryujin::InitialState< HyperbolicDescription, dim, Number >::initial_precomputations ( const dealii::Point< dim > &  )

inlinevirtual

Given a position point returns a precomputed value used for the flux computation via HyperbolicSystem::flux_contribution().

The default implementation of this function simply returns a zero value. In case of the The Shallow Water Equations we pre-compute the bathymetry.
