Hey all,

I really need your help in the plots of Electric field simulation.

for 2D:
I made simple 2 rectangle of electrodes (copper )with a circle of air around it and then used physics Electrostatics (es) and gave potential to copper rectangels and I get beautiful results of electric field distribution in 2D. I am plotting norm.E and even once put the whole expression of magnitude of E field.

for 3D:

following the same procedure, I made two cylindrical electrodes (copper) and a sphere of air around them. and when the results gave plots its almost nothing.

Please help me. I am confused and can not pin point at what I am doing wrong.

I have attached the files too
