how to customize the flux of species in Transport of dilute species?

Please login with a confirmed email address before reporting spam

Hi,

I am trying to model the adsorption of K+ on cathode by using Electrostatics and Transport of dilute species interfaces. In Transport of dilute species interface, i could choose migration and diffusion terms for the flux of species, but, I want to add an additional terms to consider the volume exclusion effect, the third term in the attached equation. Does anybody know how to do it? Thanks in advance.

Best, Feng
