Why are all harmonic indices being solved in ANSYS 9.0 for a static cyclic symmetry analysis
when the only load is an omega about the rotational axis?

When you specify the rotational velocity in Simulation with a vector, it is applied at a non-zero z coordinate,
even though this has no effect on an omegaz loading. To account for the non-zero z coordinate a CGLOC
command is used. It is the CGLOC command that incorrectly triggers all the harmonic indices to be solved.
This was corrected in ANSYS 10.0. [Ref: Defect 33263]
