Hello, I would like to understand what the solver is doing wile trying to solve a nonlinear problem. I understand I have stated in NLPARAM to star iteration at 1.0E-2. I have also activated ExpertNL In the next picture, what is the solver doing each iteration of each load step? what is changing? what Average U, Err. EPI, Measures EWI mean? WHat is the goal of the solver to notice it is reaching convergence?
