URGENT RESEARCH PROJECT: How to couple PDE's in COMSOL

Please login with a confirmed email address before reporting spam

Recently I have made quite a few posts trying to get help on solving two coupled PDE's in a self-consistent manner. My script is attached below.
I have recently made progress in the fact that I found COMSOL has an in-built for-loop iterator, which can be inserted in the solver of a study.
In the attached script I have done this, but when running the self-consistent loop it seems, that COMSOL does not recognize the coupling between the two PDE's. I have tried to include it simply by inserting u and u2, using the with() operator and even the withsol() operator but nothing seems to happen. How can I set up the coupling in a reliable way and how can I check if the solver knows to use the solutions from the PDE when solving the current one?
I would really appreciate some help on this since it is a big part of research project self-consistent modelling of the Schrodinger Poisson problem that I am currently involved in.
