  1. Campbell Diagrams are based on modal analyses, not harmonic.  
  2. You can specify rotational velocity with a commands object using the OMEGA command in a harmonic analysis.  Then you should see a frequency shift.  You can confirm that the centrifugal forces due to omega have been suppressed by doing analysis without any loads.
