I'm working on an axisymmetric model of a rod and locking collar with multiple teeth. This resembles a nut and bolt, but the "threads" of the bolt aren't helical.
I've set up contact connections between the teeth faces, but when I do a check run of the model, I get an error saying that contact is not possible "...because it is not possible for any of the elements on one side of the contact region to contact any of the elements on the other side."
If I look at the elements created on both parts, nodes don't line up in the areas of contact. I had tried this as a 3d model, and there was a pick box at one point to "create compatible mesh", but I don't see that in the axisymmetric model setup anywhere.
How do I get common nodes on the two parts so the contacts will work?
thx,
