Hi
in the eigenfrequency solver sequence (quite deep down in the solver tree), you have the option for the normalisation of the eigenvectors/frequencies, such as RMS, and model mass, once changed you need to rerun your solver, then your mass participation factors (in kg but units are not mentioned) are the SQUARE of the model participation factors (see the Structural doc)

Good luck
