I'm trying to run a electrostatic model in 3D. It has two electrodes (spheres) embebbed in air (another sphere) and we wnt to know the net electric field. When I define the boundary conditions, one of them has a maximum voltage and the other has zero voltage. I put the outmost surface to ground and run the simulation. The result of the electric field is shown (fig 2). This answer is obviously wrong, and I suspect the problem is the zero charge condition in the electrodes appear active. (see fig 1.), because, if I understand, this condition says that no D cross any surface (because 
. Could somebody help me to find where is my mistake?
