Most structural mechanics simulations are non-linear and thus convergence is not guaranteed. Nonlinearities can be a result of non-linear material models, contact, and large deformation. The goal of this presentation is provide details on how to diagnose non-converged solutions and to develop an efficient analysis process. Topics discussed include:
