global bonded contact and contact sets
global bonded contact and contact sets
(OP)
I am running solidworks simulation on an assembly. When I opened simulation it automatically assumed bonded contacts for all of the mates that I had, and it created a global bonded contact for everything. When I started going through the individual contact sets, because I needed to change/override many of these to allow penetration, I noticed that some of my screws in the assembly showed the global bonded contact as well as an extra contact set, and some screws just showed the global bonded contact set. It made me think that I needed to go through and add a contact set to each screw that does not have one. I was under the assumption that if it says global bonded under a component, then it will be bonded to any surface that it is touching. If this is true then why is there an extra contact set created for some of the screws? I uploaded a pic that shows the two screws, I did not add/change anything except the names, the contacts are all what solidworks anticipated. Thanks in advance.

It also helps to split faces on solids to isolate contact areas. E.g. if a tube end meets a plate face, I'll divide the plate face so there is a small patch that matches the tube end.
