Hi @Joyceline,

Convergence can be very tricky to solve. It will be very difficult to find the exact issue without seeing the model. From the warning messages, it looks like the contact status is changing abruptly. You can try to increse number of substeps and apply load more gradually. Also, try using unsymmetric Newton-Raphson option as you have high coefficient of friction.

Also, you can try following remedies to resolve the convergene issue.

– Adjust the Contact Stiffness
– Check for proper initial conditions/pinball.
– Change to nodal detection if the problem is at a corner
