  Dear All, hope that this post will find you well.
  I have a structure of balded disk ( 60 blade ) where I am trying to plot the campbell diagram.
  the isse is that when I am trying to resolve it just for 4 modes which are all equal to the 1st natural frequency, so technically I need more than 180 mode to get the 2nd and 3rd natural frequencies included. (effect of nodal diameter).
  for the first case it work fine but:
  when I perform the campbell diagram after extracting 180 value it crash with following message:
  "Campbell Diagram data is not complete. Please refer to ANSYS output file for possible causes." The following information is what I deduced after outputting the file from the solution branch (Write input file) and looking through the error file which says "there's no data related to the campbell diagram.
  please advice
