WebDec 16, 2024 · I have tried different strategies to get my model to converge in non linear analysis but am failing. What's strange is that it fails on a combination, but not on the load cases. This is quite urgent. I have tried the usual by increasing the load increment and number of iterations and ticking the "save results after each increment". http://server.ccl.net/chemistry/resources/messages/2024/08/09.003-dir/index.html
