I understand your point of view.

In Mech, giving Rotational Velocity to IR, OR = fix and applying cyclic symmetry and using the beta function ...so software knows i have the complete BB model.

In Fluent, similarly cyclic symmetry can be used. In Boundary condition, IR wall = RPM of IR in Mech & OR = stationary...ball I am not sure what to do...

 

But But it is a RADIALLY LOADED DEEP GROOVE BB, so NOT all balls encounter the same load and Hence, cyclic symmetry CANNOT be used.

I have tried by giving Displacement normal to the side faces (on both side) = 0 but that did not work out.

See the load distribution curve below.

Am I missing something here? Or could you suugest something for my case to model periodic movement...
