VI1 Vortex transport by uniform flow

This problem is aimed at testing a high-order method’s capability to preserve vorticity in an unsteady inviscid flow. Accurate transport of vortexes at all speeds (including Mach << 1) is very important for Large-Eddy and Detached-Eddy simulations, possibly the workhorse of future industrial CFD simulations, as well as for aeronautics/rotorcraft applications. This verification case is particularly suitable for verifying temporal order of accuracy.
