Hey Victor - I've been looking at materials where the material in the middle is weaker but more ductile than the harder outer layers. This seems to cause convergence issues that I can't seem to resolve without relaxing tolerances so much that I am g…
Thanks Victor - it seems that the zero strength value for post yield strength causes a few headaches - by setting a low, non-zero value for post yield strength the model is more stable.
BTW I'm using the demo version - does the full version have th…
