Structural analysis, Interference between components

Good evening,

 

I am having parts overlapping and interfering once I apply a force to my structure.To run a more realistic simulation I set the default interface to bonded and added fasteners from the refine model tab to simulate screws. I know that once you add a fastener the surfaces are not bonded anymore but what is the good approach to get a realistic simulation that would make the components butt against each other and don't overlap/interfere? Please see my results below. You can see the interference between the bracket and post on the left. Not to mention that the stress is highly suspicious for a 200lbf applied to the end of the bent tube which is 42" away from the upright the bracket sits on.Interference.JPG

Your feedback is greatly appreciated.

 

Thanks so much.
