Self-consistent modelling in COMSOL.

The first PDE is some eigenvalue PDE for which I can get the eigensolutions.
I now want to calculate some function p(x,y) from these eigensolutions which will enter in the second PDE, solve this and then plug the result of this back into the eigenvalue PDE.
I want to continue this procedure until a self-consistent solution is reached. What will be the simplest way to do a such thing?
Edit: To be more specific I am solving the Schrodinger equation, calculating the electron density from the eigenstates and then plugging that into the Poisson equation, which I then solve for the electrostatic potential, which goes back in the Schrodinger equation etc. etc.
Please help me in this, the litterature about COMSOL and how to set up problems like this is very poor.
