Distributed ode with convection and diffusion equation

Please login with a confirmed email address before reporting spam

Hi Guys,
I have added a distributed ode to one of my boundaries to be solved with my convection and diffusion equation. I am trying to use the difference of the average of outflow and inflow concentrations in this equation. How can I define these terms? When I use Average operators I donot get any thing. It seems my equations solve seperately.

Ode ( Ct): dct /dt = Q ( c at outflow - c at inflow)
C will be solved in convection and diffusion equation.
I will appriate if you answer my question.

Regards
