I’m trying to run an FEA on a fixed support beam, I replaced all the bolts with “intelligent fasteners”. I keep getting the “cannot process highlighted contacting surface” error

Thanks so much for replying!

I had already seen the first two posts.

I will try the Refine Model > Beam option, and see what results from it.

Thanks again for replying.

I created the beam (I think correctly), but it didn't seem to help.

Any additional assistance would be appreciated.

Certainly, I can post better screenshots. Please let me know if you would like more/better still screenshots.

Sorry, man, but you have black model with black edges. There is still 0 visibility on the problematic region. try changin model color to white/light gray. take a screenshot without first part than without the other. Describe problematic region in text and include simulation features applied to them. What kind of interface you are using. Most of the time those are tangential surfaces. But can't prove it from those screenshots.
