Relative Energy from Eigenfrequency Analysis

Hello All,

I have been working with COMSOL 4.0 (mostly heat transfer modules) but now need to analyze a structure with an eigenfrequency analysis.

I can generate the model and the eigenfrequency(s), but I would like to end up with the results presented as a plot of frequency vs energy.

Anybody know the steps I need to take using 4.0a?

Thanks Everyone
