Coupling problem: Nernst-Planck equation with Poisson not converging
Hi, I am unsuccessfully trying to implement to Poisson equation through the Electrostatic Module into the Module "Transport of Diluted species" for a stationary case. Beside those modules I use the...

Raphael: Can you please explain how your cell works in more detail? As far as I can understand, there is an inlet tube where 2 species c and c2 enter the cell and an outlet tube where they leave the...

Hi Sri, Thanks for your reply. Yes, an electrolyte with two species is washed through the cell, entering through the inner tube and leaving through the outer tube. One of the species is transported...

Hi Raphael, I was wondering if you found a solution to your problem, and if yes what the solution was because I am stuck with a similar problem and don't know what to change besides exclude the space...

Recently, in simulating Induced charge electroosmotic flow by coupling P-N-P-NS equations in Comsol, I encountered similar converging issues, and yet have not resolved~~

There is an inherent problem: N-P uses electroneutrality condition which you try to overrule by P-B. In an older version of Comsol there was physics "N-P without electroneutrality" (or something like...
