Detailed Description

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

An Analytic solution for the compressible Euler equations with polytropic gas equation of state consisting of a smooth rarefaction wave. This analytic solution is discussed in detail in Section 5.3 of [10]

Note

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

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 >.
