Hi!

I'm new to Comsol, and I'm trying to model current flow and resistance through a resistive medium (eventually, the resistance will fluctuate, and the study will be time-dependent). However, my study only outputs electric potential values. Is there a way to change the output variables/ make an equation-based output to solve for current based on resistance and electric potential, for example?

Thank you for reading my question!

Yes, it is possible. You can define a component coupling(integration) node on the domain for which you are trying to calculate the current. Name it int_surf. Then, when during postprocessing, in the expressions field, enter int_surf(ec or es. normJ).
