Inconsistent intermediate stress&displacement results.
Hello;
I am Emir. I have come across a problem in optistruct that is I believe incremenatal results were inconsistent. My model is a non-linear problem which includes freeze and friction contact as well as non-linear material. LGDISP and CNTSTB cards are active in the model. After I ran the analysis with 300N and 150 N (only load magnitude changed all the other parameters are the same). The results are listed in the rable below. Do you think I am missing something? According to the results I can not rely on intermediate results. Do I have to run new analysis for each iteration ? Thanks in advance. Have a great day.
Best Regards
| Force | Increment | Max. Disp.(mm) | Max. Stress.(MPa) |
| 300N | 0.55(%55) | 3.6 | 145 |
| 150N | 1.0(%100) | 4.26 | 248.6 |
