Initial conditions for Double Mach Reflection(DMR) problem
 
Hello everybody,

I am trying to model using an upwind convective scheme the DMR problem. But i am not sure about the initial conditions.
i readed the Collela and Woodward article called "The numerical simulation of two-dimensional fluid flow with strong shocks" and , excuse me, i could not understand the initial conditions.

I think that on the top and the bottom are periodic boundary conditions. And the inflow and outflow are too boundary conditions. But my code doesnt model well the phenomenon.

I readed the "High order finite difference and finite volume WENO schemes and Discontinuous Galerkin Methods fro CFD", from there i took too the initial conditions but it was impossible to me model the DMR.

Any suggestion is welcome!!

Regards
