Hi
The effective masses are per cartesian orthogonal directions, and each add up to Mass ="total mass" = int1(solid.rho) over all domains.
so when I ask for the mass participation factor I use (MPF_mod1.u)^2/Mass*100 to get the % of total mass per mode
so if you take a canteliever and see 20% in u (or x), at one frequency and 30% in v (or y) at another, you can see that this particular mode has its motion predominantly along x, respective y.

Good luck
