How to apply Neumann boundary condition under AC/DC electrostatic module?

Please login with a confirmed email address before reporting spam

Greetings,

I am modeling an ESP, which I would like to apply the Neumann boundary condition (grad U = 0) at both the inlet and outlet of ESP. I am currently using the zero charge boundary condition (n dot D = 0), but am not sure if this is mathematically correct.

Thanks.
