Potential Distribution in AC/DC Module, Comsol 4.3

Hey,

i am working with the AC/DC Module in Comsol 4.3. I have a formula for the potential distribution (V) and I want to calculate the electric field by using the relation: E = - grad(V).

Are there any possibilities to implement this in a 2D, axisymmetric simulation?

Thanks for help
