I've attached the geometry that im currently using along with some results that i would like to reproduce. I'm attempting to model a supersonic jet inlet around mach 3.2. I want to find the varying mach, pressure, and temperature as it flows through the inlet.

At the moment in the setup I am using an  external study for 2d and supersonic flow at mach 3.2 with gas as the fluid.

Is there anything that is setup wrong? Should this be an internal study? Not sure how the geometry would be setup if so.
