Nice tutorial. I had a question. What do those frequencies mean for fixed free and free free analysis respectively? Are they the natural frequencies of the system of free free?
Free-Free analysis is modal analysis without any constraints. Generally done to check your connections. First few modes of free-free is almost or near to 0Hz. Yes those are the systems natural frequencies.

Ok, he is a cool teacher, but i missed RB2 & RB3, MASS, etc. in the analysis another example with this elements would be cool c:
