Hi
I have a total mass of 2.217E-5 kg for clamped edge circular plate.
My MPF for the first mode of vibration are
MPFu= 4.703E-8
MPFv=1.14201E-8
MPFw=0.00343
so the modal mass I get is: (MPFu)^2+(MPFv)^2+(MPFw)^2=1.17649E-5 kg
Now the problem is I don't know whether it is correct or not as don't have any analytical results to compare with. Also, as COMSOL scales its variable, are these MPFs scaled?
