Optimization of falling sphere
-
-
Hello, I am currently working on project where a part needs to be optimized. A sphere falling from 120 meter, due to acceleration the speed while hitting ground will be 80 m/s. Now I have done this in CFD Fluent. Now on structural system I linked solution to setup, which gives me imported data for pressure. For imported pressure I have chosen surface and what should I choose for transfer definition (Inlet, Outlet, Partbody). But question comes here. For structural analysis any part must be fixed, which part should I fix to get solution done. Or is there any way to solve. All I need is to optimize the falling sphere at 80 m/s. Once structural analysis is done, I will proceed with coupling modal and topology optimization
