Free Bar Modal Participation Factor

Hello,
I am just trying to model a simple free-free bar with an analytically calculated longitudinal resonance of 509.18 Hz. The size of the bar leads to a mass of 27,000 kg and an effective mass for the fundamental mode of 1/2 that. However, when I try to pull values from the "Effective Modal Mass" or "Participation Factors" tabs the numbers are so small (on the order of 10^-5).
How do I pull this effective mass value?
Thanks
