Solving a size modified Electric Double Layer

Please login with a confirmed email address before reporting spam

Hi, COMSOL experts!
I been trying to simulate an electric double layer that accounts for species size with Transport of diluted species and electrostatics module using the build in Poisson-Nernst-Planck equations.

So far I have a 1-D model of Poisson-Nernst-Planck equation that is working thanks to all the great COMSOL community (especially R. F. Hamou!) I have attached my 1-D model

I have yet to incorporate the size effect in my simulations. I am thinking to include a concentration Global constraint in the transport of diluted species physics. Will it be able to limit the maximum concentration at electrode?
And If I want to write my own Poisson-Nernst-Planck equation on the COMSOL general PDE solver, where can I find a good guide for the new user (me) to follow.
