Dear All,

In some simulations, I encountered non-physical points in the solution and non-physical states in the upwind reconstruction. I often has this kind of behavior upon running supersonic cases yet they often go well until the convergence criteria satisfied (I used Cauchy elements here). However, for subsonic cases, this often leads to divergent. Does anyone have any idea why these two cases differ? It would also be really helpful if someone knows how to find which meshes have those non-physical states.

Thank you for your time.
