As noted in the title, I need to simulate a loop in Fluent. The problem is a transient simulation of a pipe where I need that the fluid leaving the pipe at time "n" is the feed of the pipe at time "n+1". How can I do that?

Thank you so much for your help

You could use a periodic boundary condition for the flow to exit at one end and then enter at the other end (the two boundaries that are periodic share the same faces).
