My solution is diverged when I run Supersonic Laminar flow over a flat plate. It converges till I use Mach = 0.6 but diverges after that. I tried to reduce CFL number, tried different numerical methods also, but it diverges after Mach 0.6. What could be possible error ? I am also attaching my cfg file, could you please take a look !

You could try restarting from a converged solution where you used a lower velocity, or use a different initial condition.
You could also try running it with a turbulence model, I could get a similar case running with INC_RANS + SA for Ma=2.0 |

I think the supersonic down stream pressure should not be specified, but SU2 seems not to provide such boundary condition, and i am very confused. |
