Good morning Peter. I have another problem, hope that you can help me. I've done a modal analysis of a rotating structure with different step of velocities and with solver type set to program controlled. This work without problem, but when i link this to an harmonic response, this fail and the following message appear: "MSUP harmonic do not support full damped or unsymmetric solver type of the upstream modal analysis". So i set the solver type of the modal on reduced damped and the harmonic response work, but with reduced damped i can not set on Campbell diagram and then i can't set more step of velocites. I don't know how to do.
