Flow pass jet engine

Hi guys this my first post

The story is that I am currently in third year of mechanical engineering and for my project I am looking and a jet powered vehicle and as I do not ahve a wind tunnel to do any test on it to make in aerodynamically stable so all my work is coming form fluent so everything has to be right as they are lifes at risk

Basicly I am looking a the modifications of a baseline jet powered car and I am trying to get it working in fleunt but it does not seem to work the problem occurs when I try and add boundary conditions on the jet engine and fluent does not like it. I am trying to put a mass flow inlet and a mass flow outlet one of which is not in fluent.

SO guys does anyone know which boundary conditions I can have for the jet engine?

I have tryed having a pressure outlet. it does not like it as domain has one.

Tryed a velocity inlet with having negative velocity. no luck

Outlet no luck

Tryed most of the opioions on there and nothing seems to work

Any help would be nice

Thanks

Apply PRESSURE INLET at your engine intake, PRESSURE OUTLET at the engine exhaust, and the Pressure Outlets of the domain and that of the engine should be set at different pressure settings. Also check the MATERIAL, are you using the IDEAL GAS or the incompressible air.
