Hello, everyone.

First of all, sorry for my poor english.

I'm using 2d domain to observe the shock waves around the circle.
I want to use "velocity-inlet" boundary condition for the inlet boundary, but,
according to "case check" message, I can't use "velocity-inlet" with compressible flow. So, I decided to use "pressure-inlet" .

Now, I want to know what pressure should I use as "Gauge Total Pressure(Pt)" and "Initial Gauge Pressure" ? I tried "stagnation pressure" as "Gauge Total Pressure", "static pressure(Ps)" as "Initial Gauge Pressure".But, the result is not correct.

I think, I made a miscalculate on the static pressure. I calculate it like "Pt-0.5*rou*velocity*velocity". My case is compressible flow. So, I think rou is not constant but, I don't know how to calculate the rou in mach number 1,2.

Please somebody give me hint.

Thank you all!
