    Click the Damping Ratios tab.

    • Type 0 in the first row of the Frequency (Hz) column and press Enter.
    • Type 0.01 in the first row of the Damping Ratio column and press Enter.
    • Type 30 in the second row of the Frequency (Hz) column and press Enter.
    • Type 0.01 in the second row of the Damping Ratio column and press Enter.  

    Results of all excitations from zero to 30 Hz will be based on a constant damping ration of 0.01.  The three user-specified excitation frequencies and the first five natural frequencies all fall within this range.
