We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

The shafts expand radially because rotation of the shaft is an unconstrained degree of freedom. They may not rotate at all or they may rotate at a large angular velocity, causing them to expand radially. Be sure to constrain that on each shaft, and maybe the results on the rest of the model will make sense.You could do that with a remote displacement, but it may interfere with the frictionless supports if applied to the same faces. Another way: for the general joints, set reference scoping on the shaft side and fix the rotation direction aligned axial with the shaft.
