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

Click For Summary

Discussion Overview

The discussion revolves around simulating the electric field generated by a charged sphere using Ansoft Maxwell software. Participants are exploring the comparison between analytical and numerical solutions for the electric field as a function of distance from the sphere, specifically from its surface to 1 meter away.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant seeks guidance on setting up a simulation in Ansoft Maxwell for a sphere with a radius of 10 cm and a charge of 1e-012 C.
  • Another participant inquires about the analytical solution and the user's experience with simulation software, suggesting the need for examples relevant to the geometry being simulated.
  • A participant mentions having calculated the electric field from the sphere's surface to 1 meter and expresses the intention to simulate this using finite element methods.
  • There is a suggestion that there may be existing examples in Ansoft Maxwell that could assist with the simulation setup.

Areas of Agreement / Disagreement

Participants have not reached a consensus, as the discussion includes multiple inquiries and suggestions without definitive resolutions or agreements on the simulation setup.

Contextual Notes

Participants have not provided specific details about the analytical solution or the exact challenges faced in using Ansoft Maxwell, leaving some assumptions and limitations unaddressed.

Who May Find This Useful

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?
