Beyond the remarks in the Manual concerning *DAMPING_FREQUENCY_RANGE(_DEFORM) and the notes I asked you to Google, there's nothing more I can add concerning use of *DAMPING_FREQUENCY_RANGE. If you don't see remarks on the "Iterative Method" in the Manual, please download a newer version of the Manual. As I read it, the Iterative Method makes stiffness or frequency adjustments essentially unnecessary.
