Dear peter,

First of all thanks a million for all of your illuminating answers, they were really helpful for me to know more about Ansys theory. Also, I am so glad about finding such a useful website to have a chance for FEM discussions. This model is really complicated but I learned with that without experimental data we are not ableĀ  to select the most accurate FEM assumptions. I checked the Is Solution option. wishing you a great weekend.

Best regards, Shabnam
