Hello all,

I am trying to simulate a transonic flow around an airfoil for my thesis and I'm struggling with the outlets of the domain.

There are two options that I think they are reasonable for the outlet:

- Outlet: In this option, the program runs well but it starts to create walls in the outlet due to fluid entering into the domain. CFX suggests to change to Opening option but...

- Opening: the only option to set is that the fluid is subsonic, which is not true in both transonic and supersonic cases...

What do you suggest?

Move your outlet boundary further downstream so it is not in the recirculation zone.
