      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
