It appears that the hub mass 190 tonnes is accounted for twice in the example provided (once in the SIMO body called hub, and again in a nodal component at end 1 of the shaft line). (On the other hand, the gravitational force is not included on the SIMO hub body, so the static analysis doesn't reflect the issue).
