tetrapolar electrode system

Hello,

I'm trying to recreate the model from the paper below, but I don't see how I can apply the current on the outer electrodes and measure the potential in the middle electrodes. What do I have to do regarding boundaries and stuff. Can someone help me? I have the exact geometry as in the paper below.

Kinds regards, Luuk

Hi

I would set the other current electrode to zero potential and define current density at the other one. Measuring potential between two points from Derived values --> Point evaluation. You do not need to define reference electrodes explicitly. Or if you have a reference electrode that is selective to a particular ion, evaluate its concentration and use Nernst equation.
