Fasteners

[Parsnip]

Please can some one help. I am trying to use the fasteners (screws) in Pro/Mechanica Wildfire 2.0 to attach two parts together. I assembled the model in Pro/E using mate/aligh etc, then I transferred to Mechanica and put the screws in etc but when I run the design study I just get a fatal error saying "Mechanica could not generate elements for all of the entities" - the problem is that I have no idea how to rectify this.
Any clues as to what to do, or where I can find tutorials (I have got the PTC knowledge base one but that isn't a lot of help) on how to use fasteners in Mechanica would be much appreciated.
Cheers

Before running the analysis, try the AUTOGEN to mesh the geometry and it give you some idea where create the meshing problem.

Have you checked the conectivity in your asm?, as well try to modify the aspect ratio and angles in your auto-gem, that can help you, probably your defauld is not produccing a god mesh and that is way you get this message.

I don't think it is the aspect ratio problem, since in auto-gem, if they find the required ratio is small, they will change the default value.
