How to add a constraint in Comsol.

Hi, all,
I am trying to simulate the electric field driven transport of two (inversely charged) species in the microchannel. I am using two independent Convection and Diffusion models to describe the concentration of the these two charged species (variable c and c2 respectively). How can I add a constraint such that c==c2 is guaranteed in the full domain?
Many thanks.
Z. R.
