Doing a Torsional Stiffness Study and setup the model but bringing up this error ERROR #179. I've tried to fix it over the past few days but with no luck. Wondering if anyone had any tips on how to fix this issue please let me know. I've attached the .hm model below.

As I mentioned previously, I had no issue running your model. If you are using a student license, there is a node limit in optistruct. I recommend coarsening your model quite a bit and see if it runs.
