In the real world, I have a flat steel beam that is acting as a spring. It starts out curved into a semicircular shape, and then it is loaded with a hanging weight that brings it down flat. I want to find the eigenfrequencies of the loaded spring using COMSOL. How can I do this?
I have been able to successfully find the natural frequencies for a beam that is "pre-flattened," but I don't know how to add the effects of a hanging weight (subject to gravity, of course).
I am very new to COMSOL, so I would greatly appreciate anyone who could take the time to explain this in a simple manner. Thanks!
