I'm having another try at using fasteners, but like most things in Creo it's pretty tricky without a training course or an expert on hand.
The diagnostics during meshing are returning the fatal error "Creo Simulate cannot pair the linked assembly elements near the highlighted entities. Try modifying the geometry to correct the problem." It meshes fine with the fasteners suppressed.
Here's one of the offending fasteners, with its details:
The surface highlighted to go with the error message is the face of the rear component, that the flange is clamped up against.
What's even more frustrating is that I had it working with just a couple of fasteners, so I added the rest; it then stopped working, so I tried a few things, then went back to just a couple, and now it still doesn't work!
Could someone give me some pointers on how I should be using fasteners in this situation, please? What is the mesher trying to do due to the fastener that causes it to fail?
