Reply To: FWD: Problem with Campbell Diagram

[mohammedlaminemekhalfia]

Thanks a lot for the feedback, I was waiting a lot for it.

I read the manual but it say that can not plot campbell diagram for more than 10 modes, even m disc is considered symetric but it has nearly 30 nodal diameter , I did not add the shaft as I consider that the shaft does not have anyi impact on the disc and the damping effect is negligeable !

to plot the campbell diagram for the 3rd mode in my case, I need to extract 2XNDX3 = 180 modes. I do not know if that included in the recent version or the limits on the modes number is still applied, reminding that I am using the simplest rotordynamic case.

again thanks a lot for the feedback.
