How does the Solidworks calculate the natural/resonant frequency?

Hello guys!


I'm using the Solidworks Simulation ackage to determine the natural/resonant frequencies of some cantilever beams. I have done that and it worked great, the results were very similar to my analytical results. However, I would like to understand how the Solidworks calculate that....

1 - does it apply Finite Elements (FEM) to do it?

2 - What is the "Mesh" function?

3 - If I change the Mesh Density, would it change my results?


Thank you!
