Topic: Failing sooner than expected
Hi dear all
I am modeling a column and I applied 5 step axial load first and then 10 step for monotonic lateral displacement. Almost 15 step. I check the LD diagram with experimental and all matches but the problem is that according to experimental it should not fail sooner that step 15 but mine fail step 13 and get the error that "The execution is killed due to violation of stop iteration criteria” I check the 2.4.2 of Troubleshooting and I check conditional break but I did not understand what should I do with my numbers. And I think if it fixes, the answer will be get. ( WHAT CAN I DO SO IT WILL FAIL LATER?)
I try other things and check 2.1.19 Troubleshooting and use Stiffness type: Elastic predictor, Update stiffness/Assemble Stiffness: Each step and the thing that happen is that column will not fail and at the end I received and error criteria not satisfied and I add 3 more step but It did not fail again and as I said I expect from experimental that it fails step 15 or 16. I think if I add 2 other more step it will not fail again
As I said I don’t have any idea about what number should be for error tolerance.
