Define custom equation for boundary conditon

I want to use AC/DC module to create ac voltage for my custom electrode configuration and then calculate electric field. But I want to set the custom boundary condition such as the following equation on the surface of electrodes.
∂φ/∂z=φ-V/2
(φ is potential variable and V is the applied voltage ), But I do not know how to do this.
After that, I want to use the laminar flow module and set the custom equation for the velocity of surface of electrode which is proportional to electric field (following equation) that I got it in above AC/DC module.
u=cte[∆φ ∂φ/∂r]
I was wondering If anybody guide me?
Many thanks in advance for your attention and guidance
