Boundary condition for potential in electrodeposition

Hi,
I am trying to simulate electrodeposition of metal ions on a pure metal electrode, by using the Mathematics module (General form PDE). The boundary conditions for electrostatic potential are given as 0 volts on the left boundary and "the electric potential gradient on the right boundary is maintained at a constant value" (say, 0.5 volts).
How should I represent a gradient value on a boundary? Which boundary condition should I use?
Your replies would be most helpful.
Thanks,
Nihal

Hi
Neumann condition is what you need. In general form PDE it is the Flux/Source condition. Gamma = -ux where u is the dependent variable (potential). Give a value for the variable g.
