dynamic participation ratio

dynamic participation ratio

(OP)
now I am running a structure of over 8000 degree of freedom of mass and I am trying to run 3000 modes in order to get 90% participation. However, I find it is very slowly!! i may take 250 hours to complete it. It's a half way now (1700 modes). do I have a way to know the participation ratio if i stop the program now and the computer show analysis is incomplete!

Thanks!
