Hi Jude,

I can't say much without seeing the model's settings. You may try to use a direct solver, and if the friction coefficient is greater than 0.2, you may try to use an unsymmetric solver. In addition, try to increase the number of substeps. If these fail, then try to use penalty-based contact and reduce the contact Normal Stiffness factor value, which will ease convergence.
