Detailed Description

template<typename Description, int dim, typename Number>
class ryujin::EulerInitialStates::ExactRiemannSolution< Description, dim, Number >

The exact Riemann solution.

This initial class computes the analytic solution for the compressible Euler equations with ideal gas equation of state.

Note

This class returns the analytic solution as a function of time t and position x.

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 >.
