Nyquist Plot in Electric Currents Module

Hello,

I am running EIS experiments in the lab, and would like to model my data in Comsol. I have set up my model to simulate a 10 mV DC input, however, I would like to input an AC signal and look at the frequency response, and hopefully get a nyquist plot.

How do I build this AC signal? I tried defining a global function (wv1) but couldn't figure out how to adjust the frequency, or how to use that as my input in my model.

Hi

Do you have an access to the Electroanalysis module that includes impedance experiments?

I do, but unfortunately all of my COMSOL knowledge is self-taught, and I have not been able to figure out the Electroanalysis module.
