surface accumulation in convection-diffusion model

I am solving a convection-diffusion model for 2 sub-domains, a rectangular slab surrounded by another rectangular domain. In the inner domain(slab), i am considering only diffusion and in outer domain, convection +diffusion. At the interface between two domains, i am applying a flux boundary condition (kc*(c2-c1) for inner domain and kc*(c1-c2) for outer domain). With this condition i am able to solve my model.
But now, i want to consider a surface build at the interface of the two domains (i.e. flux coming at the interface is not equal to flux going out, rather there is accumulation of flux at the boundary between two domains).
Can anybody tell me how should i take this boundary condition into account in comsol ???
Help would be greatly appreciated...
Thank you..
