How can I simulate a helix coil with current in COMSOL Multiphysics?

Click For Summary

Discussion Overview

The discussion revolves around simulating a helix coil with current in COMSOL Multiphysics, specifically in the context of modeling eddy currents in a damaged steel circular rod. The focus is on the technical challenges faced by a user who is new to COMSOL and seeks guidance on setting up the simulation.

Discussion Character

  • Technical explanation, Homework-related

Main Points Raised

  • A participant describes their goal of modeling a helix coil and applying an alternating current to it within COMSOL, mentioning previous success in modeling the coil in Solidworks.
  • The same participant expresses uncertainty about how to implement the current in COMSOL and suggests the need to add AC/DC physics to the model.
  • Another participant suggests that the original poster might find better assistance in a dedicated COMSOL modeling forum, implying that the current forum may not have the expertise required.

Areas of Agreement / Disagreement

There is no consensus on how to proceed with the simulation, and multiple views exist regarding the appropriateness of the forum for this type of inquiry.

Contextual Notes

The original poster's inquiry lacks specific details about the steps taken in COMSOL, and there is an absence of clear guidance on the necessary physics settings to apply the current.

Who May Find This Useful

This discussion may be useful for individuals interested in simulating electromagnetic phenomena in COMSOL, particularly those new to the software or working on similar projects involving eddy currents.

Hello !

I am using Comsol Multiphysics in order to simulate the eddy currents in a damaged/cracked steel circular rod, with a helix coil surrounded it and thus creating the alternativ magnetic field.

Actually, I am having a lot of problem in modelling it, mainly because I am new in using Comsol.

My first goal is to model the coil and put an alternativ current in it.

I managed to model a spring coil in Solidworks and import it in Comsol. But i cannot find how to put a current through the material in order to simulate the coil, like we can use it in a laboratory...

I guess, I have to do some things adding Physics, AC/DC, in the model. But what exactly ?

It would be incredible if you could help me, and guide me through my simulation. I need it in order to support my work about Eddy current testing. Of course, I would quote you as helpers and contact in my final work/report if you want.

Up ?
Nobody can help me ?

Maybe I am not in the right section ? I saw people here talking about comsol so I posted ... but i'll see
 
Please ?
 
You should look in a COMSOL modeling forum for the answers. There may not be anyone here who can help you.
