Hello, I have to compare the real solution of the electric field radiated by a sphere, having 10 cm radius, charged with 1e-012 C (perfect conductor), something like E=f(x) where x is distance from the sphere, from 0m (surface of the sphere) to 1m, with numerical solution. I tried Ansoft Maxwell software, but I can't figure it out how to set the problem. Any suggestions will be more than welcome. I tried a 3D model but no good solution. Thnak you.
