state_type ryujin::ShallowWaterInitialStates::SlopingFriction< Description, dim, Number >::compute ( const dealii::Point< dim > &  point, Number  t  )

inlinefinalvirtual

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.

Implements ryujin::InitialState< Description, dim, Number >.

auto ryujin::ShallowWaterInitialStates::SlopingFriction< Description, dim, Number >::initial_precomputations ( const dealii::Point< dim > &  ) -> typename InitialState<Description, dim, Number>:: initial_precomputed_type

inlinefinalvirtual

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. In case of LinearTransport we precompute the advection field.

Reimplemented from ryujin::InitialState< Description, dim, Number >.
