So for my graphics class I am currently reading "Stochastic Dynamics: Simulating the Effects of Turbulence on Flexible Structures" by Jos Stam
However, while starting to implement it, I've realized my understanding of math is not strong enough to fully understand what is going on so I have a couple of questions.
Given the mass matrix M and stiffness matrix K, how would I go about solving MQD=KQ where Q is the modal shapes matrix and D is a diagonal matrix of modal frequency involved with Q. I am not sure how Q and D can both be found from this one equation and exactly what part of this problem is a eigenproblem.
I am told that I should use ARPACK(which according to the paper uses Lanczos method) but without first understanding what is going on in that equation, I am not sure how to proceed. I would like any help or hint on understanding this.
