2D Euler equations - Forward facing step

Problem description       Results:   2 Levels        3 Levels

A stationary mach 3 flow hits a rectangular step. A stable shock-wave pattern with a characteristic mach-stem top of the corner develops after a few time units. This well-known test problem problem demonstrates AMROC's capabilities for multiblock domains. No special entropy correction is applied to cells at the corner. Instead, a numerical method with higher numerical dissipation is chosen to obtain a stable solution.
