Current flowing in resistive material how to find surrounding field

Hello, I have a simple model (attached) where I have a aluminum disk that has two contact potentials and current flowing through it. Eventually I would like to add other grounded electrodes in the...

Re: Current flowing in resistive material how to find surrounding field

Hi Adam, in the electric currents application mode COMSOL has problems with zero conductivity domains. So you must assign a very small, but non-zero conductivity to the air dpmain. I tried with 1e-99...
