I created a simple reinforced bolted box in order to analyse it statically but the software gives me an error where my assembly is not well fixed and stable. I also tried using soft spring to stabilize my model, but still no result. Any help would be appreciated.
I have another question too eventhough i know it has been asked before but i didn't get any result. May I use bolt connections if i change my elements to shell? (because i analyse it now as a solid element.)
Thanks a lot.
