Equations to be solved in a FE solver!

Equations to be solved in a FE solver!

Hello; I have a basic question from FEA theory.
What are the basic equations solved during ..
a. Linear Static Analysis
b. Nonlinear analysis
b. Dynamic Analysis
c. Crash analysis
d. CFD
e. NVH

Thanks in advance.

RE: Equations to be solved in a FE solver!

Thanks for your reply. I'll have a look at this article but my question is what is the basic equation solved during NVH analysis?
As you know, in linear static analysis the basic equation is Kd=f; or for modal analysis we have M*ddot(x)+ K*x=0;


RE: Equations to be solved in a FE solver!

Is this a homework question?

(2B)+(2B)' ?
