      Hello, I have a project that I'm having troubles with. I am a beginer using ansys and I can't figure out what I'm doing wrong. In my project I have to simulate a ship propeller (for a general tanker - 21000 TDW) in fluid flow(fluent) and static structural. The type of ship mentioned above should not exceed 15.1 knots using a 2 stroke low speed diesel engine. I imported the propeller from grabcad and started working. I attached photos with everything I did, including the propeller design.
