Ship hull with external and internal flows
 

Hello,
I’m trying to simulate a case where a ship hull has ducts to communicate front water from the bow region to the propeller at the stern to reduce wave-making drag. In this scenario there are 2 flows affecting the hull, external (the ambient water) and, internal (the suction of the water by the propeller) any advice about the setup will be appreciated.
