Hello,

I have a 2D simulation of two electrodes in contact with a conducting material which uses the AC/DC module and the frequency-domain study. One of the electrodes is configured as the terminal. In the other electrode, I would like to establish a Distributed Impedance to behave as a constant-phase element (CPE), as to resemble the electrode-electrolyte double layer.

The CPE impedance:

Using the formula provided in the Distributed Impedance:

I can define my parameters as:

Question: Is it possible to define a frequency dependant parameter (e.g. ) on the Frequency Domain Study? If not, is there another approach to this?

Thank you.
