Detailed Description

template<typename Description, int dim, typename Number = double>
class ryujin::InitialValues< Description, dim, Number >

A class implementing a number of different initial value configurations.

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

For validation purposes a number of analytic solutions are implemented as well.

Member Function Documentation

◆ parse_parameters_callback()

template<typename Description , int dim, typename Number >
void ryujin::InitialValues< Description, dim, Number >::parse_parameters_callback

Callback for ParameterAcceptor::initialize(). After we read in configuration parameters from the parameter file we have to do some (minor) preparatory work in this class to precompute some initial state values. Do this with a callback.

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 the function signature has an additional parameter t denoting the current time to allow for time-dependent (in-flow) Dirichlet data.
