… Check results carefully. Refer to Troubleshooting in the Help System for more details.
During the solution it was found that one or more of the contact pairs was not initially in contact. You may check the solution output located in the Worksheet of a Solution Information object to determine exactly which contact pairs are initially open, and take the appropriate action.
This message is expected if a contact pair is meant to be initially open and may become closed after the load application.
If initial contact was desired and the contact pair has a significant geometric gap, setting the manually to a sufficiently large value may be required.
If symmetric contact is active, it is possible that one pair may be initially open and its symmetric pair be initially in contact. Check the solution output to confirm this.
