Detailed Description

template<typename Description, int dim, typename Number>
class ryujin::ShallowWaterInitialStates::GeoTIFF< Description, dim, Number >

Returns an initial state by reading a bathymetry from a geotiff file. For this we link against GDAL, see https://gdal.org/index.html for details on GDAL and what image formats it supports.

Member Function Documentation

compute()

template<typename Description , int dim, typename Number >

state_type ryujin::ShallowWaterInitialStates::GeoTIFF< 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::GeoTIFF< 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 >.
