Hi All

I am a new SU2 user, trying to solve a 2-D supersonic cylinder problem with DG solver - fem_navier_stokes. When SU2 read my 3rd and 4th order mesh it always reports an error message "negative Jacobins found", and the simulation terminated. Can anyone bring me some suggestions with my mesh design?

I generated my mesh via Gmsh. The function "set order 3" were used after my mesh generation. The Gmsh script is attached.

I am sorry, I do not know what is 3rd order mesh.
