Electrostatics Non Zero Values

$

Hello, I have run some static module-based models and have tried to look at 2D graphs of potential and electric fields.

I have set up a parameter scan over a series of initial voltages and tried to consider primarily how the electric field changes. I especially want to only see what changes from the ground state to zero voltage. Finally, I used a join to eliminate my first parameter scanning solution from all other solutions.

The problem I have found is that when I consider the case with 0 volt applied I still see the feature. In potential, there are small variations in order from 10 to -11 / -12 and then in the electric field, I get the strong improvement of the field near some metal components that I have models. The reduction in the size of my mesh elements seems to be helpful for one point, but I feel I have reached the computer memory limit so now I stumble.

(Another thing I found was while trying to look at the electric field I put in the formula abs () so that I could look at the magnitude and try and see more clearly, but I found I still had negative values .)

I don't understand why I get these things when I can say I'm subtracting the same set of data from itself. It may be the case of a simple mistake or misunderstanding but any insight or assistance in how to solve this would be greatly appreciated.
