error of local variable perm referenced before assignment

Post by FaizanAhmadNadeem » Thu Mar 23, 2023 8:42 am

Hi STKO team,

I want to model the thin cylindrical shell representing the tunnel by shell elements Shell-DKGQ or shellMITC4 with plate fiber sections, but most of the time I am getting an error of local variable perm referenced before assignment. I am not sure why it's happening! can you please guide me what I am doing wrong?

I have attached a model with this query!



Thank you in Advance!

Hi FaizanAhmadNadeem,
Pay attention when you assign the element property. Use the selection button (only face) and not edge and vertex in this case.
I attached the corrected model.

Best,
Valentina
