Add_sm_st: coefficient should be 0

I have an analysis that will not complete. I’m unsure if it’s lack of convergence or something else.

To check: Torque follows right-hand rule when applied to a reference point, correct?

I’d welcome any comments on my setup in general

EDIT: I had a larger surface body that was continuous between the no disjointed surfaces. I kept getting negative jacobian errors. Trimming the surface changed where they occured, but they were never in critical areas, so I trimmed everything away that doesn’t matter.

Well, it’s still the same problem: Error creating a section - #5 by FEAnalyst

First of all, add BCs to the unconstrained directions of the rotor. Then try with prescribed rotational BC instead of a moment. At least to establish contact and get rid of initial rigid body motions. But you should consider approaches like using compression-only constraint, springs or non-shell stoppers tied to the rotor.

Yes, the direction of rotation can be determined using the right-hand rule.

Thank you…
I swear I tried that and it failed - but that was probably back when I was getting jacobian errors from my mesh. I just re-tried it and got results that make sense.
