Introductory tutorial to the RF Module

Please login with a confirmed email address before reporting spam


I want to calculate the eigenfrequency of a coil. I followed the introductory tutorial to the RF Module and found a frequency of about 9.8e6.

But, for COMSOL to be able to calculate this frequency I had to tell it to search for eigenfrequencies around: 1e7. If I tell it to search around, let say 1e6 I get this " the relative residual is greater than the relative tolerance" error or the "The relative error is greater than the relative tolerance" error. Is 1e6 really to far from 9.8e6?

My question is, what do I do if don't have a very precise idea of the eigenfrequency value? Is there a way I would not have to guess to much?

best regards,
