Hi,
I followed the paper in the past as well, but what I used was the model of "electrostatic" or "PDE coeff form" directly. I did not try to use"conductive media DC" to solve this problem before. I m wondering how you define the subdomain for the electric problem so as to solve phi (i.e. zeta in ur own equations) with ur BCs? What I can figure out at this moment is that the gradient of phi should not be zero at non electrodes, but the normal factor is zero. Also, ur Jn eqn at electrode boundaries seems not to establish a pde for solving phi at electrodes, so the subdomain function (supposed to be the laplace eqn involving phi) is not associated with boudnary conditions. That is my opinion and I am still new to Comsol too.
Regards
