So far, only the original Roe scheme has been implemented, so the validations are done with this scheme.
The first validation case is resolving the oblique shock over the wedge of course:
Mach 2.36 Flow over a 20° wedge (Inviscid flow)
The wedge angle and Mach number are chosen such that the shock angle becomes 45° according to the 1-D oblique shock analysis (κ=1.4). Since the domain is a square, it is seen that the shock extends from the tip of the wedge (the domain center) to the domain corners.
