I also found an issue in the analytical side of things
So far, I have been experimentally getting my natural frequency and then deciphering the properties using omega = sqrt(k/m)
But this site tells me otherwise:

I compared the stiffness values of my 3d solid model by giving an element a simple displacement and then also getting the history output for the reaction forces on that same element. The sitfness was off by a mangtidue and also on the values (so completely wrong)
Not sure whats going on!
So here's the plan:
1) Double-check my units
2) Create an RP in space such that it matches the Center of Mass for the accelerometer
3) Zero mass density for the beam
4) Kinematic coupling for the RP and the nodeset where the accelerometer is supposed to be sitting
5) Point mass/ inertia on the...
I have a simple problem: a cantilever beam with a tip mass of 0.0634 Kilograms has some vibrational response from an impact, and from that data I used a FastFourierTransform to get the natural frequency, which turned about to be 10.5882 Hz. And the beam's dimensions are as follows - L = 0.186 m...
