How to set injection on surface(plane) with pressure inlet boundary condition?
 

Hi! I'm pretty new in Fluent and I want to simulate injection to external region from the body.

The purpose of simulation is the validation of previous study. From the reference, author used pressure inlet boundary condition as a injecting method.

So here is my question, is there a way to determine the Mach number(In my case ,M=1) while using the pressure inlet?

I've tried a few times, but I can't find a way to specify Mach numbers in the pressure inlet.

Thanks for your help in advance!
