Hello,
I am trying to model a bolted connection with two RBE2 spiders (one for a threaded surface, one for a washer surface of the bolt). I connect these using a beam element split at the center.
The connections work great without preload. I have problems when attempting to apply preload. I have tried the utilities and tools preload options, neither have worked. I tried to split my beams manually and use overclosure MPC to tie them, apply BC and loads to the control node manually and no matter what I try, I can not get the preload to apply.
I have tried to mimic the solution found in a separate forum linked below (sol400 bolt) and had no luck. I have attached my file for reference. Thank you for any help you can offer!
