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.

      One possible cause is that the edge nodes are attached to elements with only a translation dofs, but there are elements in the model (e.g., beam or shell) with translation and rotational dofs. If so, the solver will write cyclic symmetry constraint equations for non-existent rotational dofs. This problem can be alleviated by using the CYCOPT command to specify the dofs to be used. For example: CYCOPT,DOF,1,UX,UY,UZ ! For pair 1 CYCOPT,DOF,2,UX,UY,UZ ! For pair 2
