Finite element simulation of a solenoid

Click For Summary

Discussion Overview

The discussion revolves around the finite element simulation of a coil in a time-varying magnetic field, focusing on how to model a coil with several thousand turns and the implications of the coil on its surroundings.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant seeks advice on modeling a coil with several thousand turns in a finite element simulation, considering the use of a cylinder and anisotropic material parameters.
  • Another participant inquires about the use of the program MAXWELL for this simulation.
  • A different participant mentions that while MAXWELL can define solid cylinders as coils, this feature is not available in the software they have access to, prompting a question about how MAXWELL implements this functionality.
  • One participant shares their experience with simulating a solenoid in MAXWELL, noting that they assigned the current excitation as the product of the applied current and the number of turns, with the solenoid modeled as a hollow cylinder.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the best approach to model the coil or the specifics of using MAXWELL, indicating that multiple competing views and uncertainties remain.

Contextual Notes

There are limitations regarding the availability of certain features in different software versions, as well as potential dependencies on material parameters that have not been fully defined or agreed upon.

Hi all.

I would like to do a finite element simulation of a coil in a time-varying magnetic field, to see how much current is induced in the coil, and also to see how the coil itself affects its surroundings. Now my question is, how do I model a coil with several thousand turns in a practical finite element simulation? I was thinking that maybe I could just draw a cylinder and assign some (possibly anisotropic) material parameters, but then what should these be? I hope someone has an idea!

Do you know how to use the program MAXWELL?
 
I am aware that Maxwell has some way of defining solid cylinders as coils, but this functionality does not exist in the software I have access to. Do you know how Maxwell implements this feature?
 
The last time I simulated a solenoid on MAXWELL, my assigned current excitation was the product of the applied current and the number of turns. The solenoid was a hollow cylinder with the excitation applied in the direction of the flowing current.
