Ansoft Maxwell guidelines -- Simulate E(r) for charged sphere

  • #1
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.

Thank you.

Welcome to the PF.

What do you have for the analytical solution?

What experience do you have with simulation software like Ansoft Maxwell? What example simulations can you find with that tool for similar geometries?

Hello
I've just started using this software. For analytical solution I have the radius of the sphere r=10cm; the charge q=10^-12 C, and I calculated the electric field from the surface of the sphere to 1 meter from the sphere. This evolution I have to simulate using a finite element method software. I know Ansoft MAXWELL using this method for simulations.

There should be some good examples available with the software that are close to the geometry you want to simulate. What have you found in the way of examples? Can you post some links or screenshots for the examples?
