Hello there!
I was making 2 domains inside a fluid domain and defined one of it as inlet and the other as outlet. But once i tried to running it, the flows didnt go out thru outlet as i defined before.

I made 3 mm gap between drum and housing domain so the fluids could be able to moved into the drum and expectedly to go out to outlet.

But its just hit the drum and nothing happened, do you guys think i miss some boundaries or my geometry is not correct at all?

I attached a picture here.
