hey guys,
I need your help.

first:
my main boundary condition is the velocity, but I have
a pressure (6bar) too.
if I fix the pressure as a 3d-fluidpressure at the inlet the solver dont get
the 6bar and ignore them at the results.
How can i manage this?

second:
my fluid is air.
I want to calculate compressible, for that I use the Coupled
Thermal/Flow solver.
But in the results dont have any differents to the normal Flow solver.
My temp., pressure & density are unchanged.

Here I have two screenshots of my mesh with the boundary conditions at the inlet and outlet (ambient)

thanks for your help
greeting
