Ansys Maxwell 2D Number of turns

Click For Summary

Discussion Overview

The discussion revolves around defining the number of turns in a coil designed for operation at 100 kHz using Ansys Maxwell 2D. Participants explore how to represent coils in the software, particularly in relation to magnetic flux calculations and post-processing methods.

Discussion Character

  • Technical explanation, Conceptual clarification, Homework-related

Main Points Raised

  • One participant inquires about how to define the number of turns in a coil within Maxwell 2D, noting that the software treats coils as a single conductor.
  • Another participant compares Maxwell to Comsol, suggesting that in Comsol, a toroidal shell is identified as a coil with assigned turns and current direction, implying a similar approach might exist in Maxwell.
  • A participant mentions they figured out how to integrate the number of turns in Maxwell, stating it performs post-processing similar to Comsol.
  • Another user expresses a similar issue using Maxwell 3D in magnetostatic mode and requests clarification on integrating the number of turns.
  • One participant advises that to obtain correct magnetic flux, the current should be multiplied by the number of turns when assigning excitation, and provides steps to define the number of turns in the setup and post-processing tabs of Maxwell 2D.
  • A later reply confirms that the same approach appears to apply in Maxwell 3D.

Areas of Agreement / Disagreement

Participants share similar experiences and approaches regarding the definition of turns in coils, but there is no explicit consensus on the best method or whether the same techniques apply across different versions of the software.

Contextual Notes

Some participants reference specific features and functionalities of Maxwell 2D and 3D, but details on the integration process and its implications remain unclear. There is also uncertainty regarding the applicability of methods across different software versions.

Who May Find This Useful

Users of Ansys Maxwell, particularly those working with coils in electromagnetic simulations, and individuals seeking to understand the integration of coil parameters in simulation software.

Hi,

How do you define number of turns in a coil designed to operate at 100 kHz? Maxwell 2D axisymmetric treats the coils as a single conductor, how can we define number of turns. I would appreciate any response.

Thanks

I don't know Maxwell but in Comsol you simply identify a toroidally shaped shell as being a "coil" and assign N turns plus a current direction (as a cross product orientation) as a property to it. IR losses are determined by the resistivity of the material assigned. The simulator "cheats" and simplifies the B calculation based on circular sheet currents in the structure and multiplies by N.

I'm guessing that Maxwell does something like this.
 
Thanks for the reply. I actually figured out how to integrate the number of turns (integrate N on the matrix) and maxwell does exactly the same thing with comsol and call it post processing.
 
Hi tya1010. I'm having the same problem you had (with the difference that I'm using Maxwell3D in magnetostatic mode).
I'm still learning to use this software. Could you elaborate on "integrating the number of turns"? or point me to where you found that information?
Any help with be highly appreciated.
 
Hi,

To get the correct magnetic flux you need to simply multiply the current with the number of turns and enter I*N when you are assigning excitation. Apart from that for the correct results (for example L) go to parameters and there is two tabs one set up and the other one is postprocessing after you check the box include under set up then under postprocessing tab you can define the number of turns. These are all done on Maxwell 2D so I am not sure if it would work on 3D though.
 
Makes sense. As far as I can see, It's the same in Maxwell 3D.
Thank you very much!
