Hi, im doing vibration analysis on rotor dynamics problem. It consists of a long shaft, two bearings and one disc. im performing modal analysis for a particular spin velocity. The problem consists of 6 elements all together.

My actual question is,

1.How can i extract the Stiffness, Mass, and damping matrices of all the individual elements seperately?

2.How can i extract the Global assembled matrix of the problem?

………… IT WILL BE VERY HELPFUL IF U SHARE YOUR IDEAS HERE…

THANK YOU…….
