Diagnosis of "no convergence of nonlinear problem robot" issue.

takundat1 · ‎08-01-2022

Hi All,

I need help to figure out why my models are not working. Both of them have reported "no convergence of nonlinear problem". I did the second (UNDP Portal Frame Structure Rev 2) one as a control to the first and I got the same result. My manager also made an attempt but wasn't successful. Please find attached the link to the the models:

The help would be surely appreciated.

Regards,

Takunda.

Hi @takundat1

Check "Matrix update after each iteration" in Nonlinear Analysis Parameters for each non-convergent case.

You can do it quickly for all cases on selection.

To complete @okapawal 's comments:

- Add selfweigth sof the structure to the case #1

- Add some posts to the horizontal bracings

- Set simple cases 2 to 10 as "auxiliary
