Something that's bothering me

Hello, everyone. When I used the LF electrostatic module to solve and calculate, there were many times when there was no result. I don't know what the problem was. In addition, after I use a module to complete the solution, after the cloning operation, there are two completely different results, I do not know what to do

I would double-check that the electrodes being used are added as voxels correctly if they're not then the boundary conditions do not get set up properly.
It might be easier to help if you provide more information.
