Hi everyone,

I read all the posts about Modal Participation Factor. I understood that for one direction the sum of all the MPF will give us the total mass thanks Ivar.
The fact is that I'd like to get the modal mass for one mode and can't manage to do it. I mean, how from the 3 MPF (MPF_u, MPF_v & MPF_w) for one mode I can get the effective (modal) mass for this mode?
I don't know if it's really clear, I can precise my question if necessary.

Thank you to everyone who could help me,

Jean
