So, inspired by Roland Jakel's presentation, I thought I'd revisit an old analysis and try to re-run it using the fastener functionality.
Unfortunately, the analysis ran with "The fastener is invalid" warnings, and resulted in no loads (despite specifying preload).
The model is slightly unusual in that there is a deliberate gap which the bolts should pull down once tightened, so I closed the gap to make the surfaces coincident, but this made no difference.
The clearance holes are chamfered on both sides, so I suppressed these chamfers (and reinstated the gap) then redefined the fastener references, only to be told that "The fastener references cannot lie on the contacting surfaces." Well, a) there's a gap so technically the surfaces aren't contacting, and b) how else am I supposed to select the references, if I can't select the open edge of the tapped hole?
On a related note, it tells me that I can't put a 6 mm fastener into my M6 tapped (Ø5) hole - should I be modelling my tapped holes at the major diameter, or is the root diameter of the screw thread appropriate?
