I'm having trouble with a surface contact. The analysis is a three part assembly. I've recreated the contact several ways with no luck. The analysis is MES with nonlinear Material. I made a change to the original dwg I was opening and it no longer working. To be clear, I renamed the original, modified it, opened new file in simulation and recreated everything for the analysis. I'm wandering if the radius next to the surface have any part in causing the problems I'm having. When the analysis is ran the 800 part(blue) moves thru the 100 part(yellow) like it's not there taking the 400 part(black) with it.
Above is my latest attempt using a surface group.
Thank for your help
I first began with two contact surfaces. When that failed I found one of your post suggesting using a surface group. Sadly it failed too. I ended up removing the radii and replaced them with a chamfers. After that the analysis started working correctly. The real kicker is it use to work with the radii and only selecting the two mating surfaces.
Thanks for your help
