Tarin is on a distinguished road
I am trying to simulate a pipe rotating around de x axis (see, please, the drawing attached). I have defined "A" as a mass flow inlet and "B" as pressure oulet = 0

Can anyone tell me if I have to select mesh motion or frame motion in cell zone condition? And which is the difference between them?

(I have tried both and they give differente solutions concerning to generated pressure)

Thank you!!!
