Contact with shell elements

  Hello,
  I have a problem with a contact between two parts modelled with shell elements.
  The two parts are connected with a bonded contact (edge/edge).
  When I start the analysis, I get an error message which reports a rigid body motion.
  I will be grateful for any help you can provide. Thank you.
  Regards

  Hi crl_mb
  I looked into your model and can see that the problem deals with edge to edge contact in shell. This makes it a relatively tough problem for convergence.
  Further, I made a couple of changes which helped convergence.
  1. Used 2 separate bonded contacts for the two edges
  2. Increased the pinball radius.
  I am attaching the updated model for your reference. You can solve the system and see if this works for you.
  Best Regards,
  Gaurav
