Primary Currents for 3 electrode system

Please login with a confirmed email address before reporting spam

Hello, I am trying to simulate a sensor design for my research. My sensor consists of three electrodes which I would like to study the primary current distribution within the electrolyte. I have uploaded a .jpg identifying my three electrodes.

Every time I try to perform a study, it results in an error:
Failed to find a solution.
The relative residual (#) is greater than the relative tolerance.
Returned solution is not converged.
- Feature: Stationary Solver 1 (sol1/s1)

I am not sure how I should be tweaking my model to get it to run. Can anyone help me out in how I am defining my physics to get a converging solution?

Hi

Is that a dilemma that you are applying primary current distribution also in the domain that has been defined isolated? Also, the reference electrode does not participate in the current conduction. I have not tried this but should it also be isolated?

Lasse,

I am honestly not very sure when you say that I have defined the currents in a domain that is "isolated." I am not seeing where in my model I have defined any physics as such. Maybe you can point out where I can fix this?

Hi

You have primary current distribution also in the glass substrate and in the reference electrode.
