How do i just set pressure as inlet??
Does I only remain velocity as zero and set my initial gauge pressure as my inlet??

Use the "Pressure inlet" BC for the faces which you want to set as an inlet.
You needn't set anything about the velocity magnitude, but just total pressure and flow direction.

hello,
I want to analyze a centrifugal compressor in fluent.
I choose 30,000 rpm as my rotation velocity. and I want to predict outlet pressure. how can I do this?
what is the correct BCs in inlet and outlet?
you can see my geometry in below picture.

thank you very much
Farzad
