I would like to define the outlet bc as supersonic outlet. In user guide, noted that "Should the flow become locally supersonic, the specified pressure will no longer be used; pressure will be extrapolated from the flow in the interior. All other flow quantities are extrapolated from the interior." However when i changed the value of outlet pressure for my supersonic case, the exit mach number is changed.
I will be pleased if anyone can clarify this issue

At the outlet / near the outlet is the flow subsonic?

Domain is entirely supersonic :)

If you just check all other properties and velocity fields: any difference. I can think that it is a post-processing issue wrt Mach number.

my case is hypersonic internal flow. So i am sure that my flow is remained supersonic throughout the domain. While i remain the pressure outlet as default, no error is occured. This may be correct but not sure

As mentioned in my post if velocity field and temperature field and pressure field are not changing then I guess it is a post-processing issue. Please check that.
