Specify a cyclic symmetry analysis (CYCLIC) before meshing the cyclic sector.

The program can then automatically create matched node pairs at the low and high edges, providing the most accurate results from a cyclic analysis (AMESH and/or VMESH).

Use caution when applying boundary conditions on a cyclic sector.

For example, applied boundary conditions (D) and/or loading (such as SF) on the cut boundaries of a cyclic sector model are not applicable.

In a harmonic or static cyclic analysis with non-cyclically symmetric loading, all applicable harmonic index solutions are constructed automatically.

It is not necessary to specify the harmonic indices (CYCOPT).

Use the linear perturbation procedure for linear or nonlinear prestressed modal analyses and harmonic analyses.
