BI1 - Inviscid vortex transport

The test case concerns the long term transport of a vortex by a uniform base flow over a quadrangular, doubly periodic domain. 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 test case has been part of the workshop since the beginning, so participants are requested to use at least the meshes from the previous workshops.
