Hallo
I have conducted a static analysis on a beam of thickness 5mm. Below are the results. The beam is symmetric about YZ plane. I have used Ux = 0, on the left model at the symmetric plane. i want to know why there is a difference in the results, when it is symmetric in nature. I have attached the model file for your reference. Please let me know where i must do changes.
Thanks
