Hello, I'm designing a bearing in ansys Rigid Dynamics and encountered the error "Only rigid bodies and flexible bodies which are used in Condensed Parts are allowed in the current analysis". I scoured the entire Internet trying to solve this problem. I tried different types of contact and joint.
My bottom cover is a rigid body, (part of the ground) is a separate component, the balls are a separate component (shared topology - shared) and the top cover is a component. As far as I know, a component in geometry is a condensed part. What should I do? Thanks in advance.

Hi

The message is I hope clear I believe (flexible bodies need to be condensed parts).

There are some tutorials online about this and how to define condensed parts.

Thank you! This really helped solve the previous problem. Now I organize the movement of the balls through friction, and not through joint. But now the old problem has appeared in a new place. Shaft+Screw is a body that is part of the Shaft+Screw+Up part via shared topology – shared. As far as I understand, the program requires that I also make Up part of my Codnensed part, and when I do, an error appears about the contact between the Condensed Part and other bodies (Balls, in my case). Joint – Moment force applied to the body Shaft+Screw. What should I do? Thanks in advance.
