Hello,
I need to simulate a pipe rotating around its axis and see how the flow rate comes out through the outlets that are on the wall of the pipe.
My question is, the only difference between reference frame and direct rotation is when is it used? The reference frame in steady state and the direct rotation in transient simulations? Or can I use direct motion in steady state as well?
What are the other differences and how do I choose which one to use?
Attached is an example of what I would like to simulate.
Thank you.
