According to PLCAMP documentation for the new ANSYS 10.0 command PLCAMP, a comparison between complex mode shapes is used to track the modes versus the rpm excitation axis. Could you provide further information what is done here for my advanced dynamics seminar? Is it a sort of MAC (modal assurance criterion)?

You are right. We are using the modal assurance criterion to compare the complex mode shapes at 2 different load steps. If the result if less than 0.7, we issue a warning to let the user know that sorting may not be satisfactory.
