Hello Nanda,

Thank you for prompt reply. As you mentioned, in step1 I used 'Adjust to touch' with frictionless condition, but it didn't work. Ring didn't diform at all in step1 itself, refer attached image. There is non-uniform gap between two bodies. If you see the inital geometry there is gap along minor axis (Horizontal) and penetration along Major axis (vertical). 

Step1 with frictionless and 'Add offset, Ramped effects' is working very well. Can you suggest me different setting for step2 i.e. Bonded. in bonded we don't have any option for interface treatment and initial contact status for both is showing 'closed'. so the value of pinball radius is sufficient.

Is switching from frictionless to bonded making things difficult.
