Joint for a ball in a bearing

  Hello,
  I am performing an RBD over a bearing.
  1. The fixed support when dropped in the Analysis section, it shows DOF undetermined but the drop down options show nothing. Is it okay not to include it inside the analysis settings?
  2. Should I also have to give individual joints for each ball ?
  I get an error which says “Body ball (1,2,3..) is not linked to any other body by a joint”.
  Please help.
  
  Regards,
  Shahul

Hello Ashish,
Thank you for the video. As you may have seen, it is a static structural analysis and he gave a wrong joint (He said revolute but he used fixed joint). But I am trying to achieve more like the video I added below:

The screenshot is the one with my boundary conditions. In contacts, I gave automatic contacts and seleted no separation. Please let me know what else is to be added.
