Don,
We had a similar meshing issue - inexplicably, suppressing the cyclic constraint allowed it to mesh, and after resuming it still meshed!
Chris,
I've used cyclic symmetry plenty of times before and I hope I have a good understanding of what it does - why do you say this is applied incorrectly? The model and loading has two-fold rotational symmetry as far as I can see.
The axis of revolution along a common edge shouldn't be a problem - in principle this is no different to analysing a 'wedge' of a solid shaft, except that in that case there would be no need to explicitly specify the axis, as Mechanica would infer it from the two selected 'sides'.
You're spot on, it is a roller bearing skew problem. My colleague started with Hertzian calcs but found they only seemed to give sensible numbers for very large skew angles, ~25-30° and larger - at small but non-zero angles the results didn't seem believable.
Do you have a good resource for skew-cylinder Hertzian formulae?
Thanks,
Jonathan
