Question: How to connect an element that allows full rotation with only one screw?

Answer: For the case of connecting elements with only one screw for full rotation, it is necessary to first review and adjust the Model type of the element being connected.

If you leave the default setting N-Vy-Vz-Mx-My-Mz, meaning that the element transfers moments as well, you will get a mechanism (rotation around the screw) and the calculation will not be feasible.

Therefore, it is necessary to change the Model type and disable the transfer of moments for the respective element.

This way, the analysis will be properly conducted.
