Hey peteroznewman.

I have been asked to provide the first 4 natural frequencies and compare it with analytical finite element method. so in the analytical Method i get the Following:

F1:18.611, f2:116.638, f3: 326.59123, f4: 639.988
so im worried My Modal analysis is missing something. Excuse the ignorance as i have just started this course.
thanks
