Hi Guys!! I´m trying to simualte a cylinder with another one inside, the big one contain air that will pass inside the smallest through a hole on the surface of the last one.

Anyone know how to do this?

As mentioned before....... Create a B-rep solid for the large cilinder and a second B-rep solid for the smaller one. Then create the main fluid domain in the first solid. Create a fluid sub-domain for the second solid. Create a thin surface (wall BC) on all surfaces of the smaller cilinder, except for the hole.

Are you facing difficulties here?
