okaay great, so can i just take the absolute value as the eigenfrequency to work with?

Hey, Im working with Comsol and doing some eigenvalue analysis. Why is sometimes the eigenvalues are complex numbers and not real number frequencies? How should I interpret these complex eigenvalues? Thanks

oh i figured out what's going on, you can only draw lines like that in 2D..I was working in 3D all the time. But I guess Comsol doesn't allow you to do that in 3D just yet, huh? Thanks for the help!

hmm..yeah i know you just click the "line" tool. But when i click that I have to enter coordinates to specify my line. I was looking for a way to just draw a line on the workbench itself by just clicking anywhere and moving the mouse...like how some CAD programs are.

so how exactly do you just "draw" these lines? I always see the option to enter coordinates

Hi, I am pretty newish to comsol. Im having a simple problem in constructing my geometry How exactly can you draw lines from one point to another when you don't know the coordinates of the points? My geometry is pretty complicated and its difficult to find the coordinates of the points. So is...
