Open the initial project (flux_static.FLU)
Run the python script:

Hey,
The project file is attached.
After some more tries I did a magneto static 2D analysis and I've got the flux and the magnetic flux density, but it still need the force on the coil and the torque on the shaft as a function of the rotor's angle and there are still errors.
Thank you for your time.
Hi,
Thanks for sharing the project. Analyzing the project I found that you use several mechanical sets. In your case you need to use two mechanical sets, mobile and fixed. You will find that I delete al the mechanical sets, I keep just two that I use in the face regions.
About the geometry, I modified it slightly because it is not symmetrical as indicated in the picture you sent. Also I create a new face region (mobile_air) to surround the moving part.
To compute the force on the coil, you need to create a sensor. To do it :
For the torque, once the project is solved, in curve select new curve. A window opens, select Mechanical set: electromagnetic torque.
Best regards.
Hi,
You are welcome. I used Flux 2018.1.3 , maybe this is due to the fact that you are using a student version.
I create a python script to modify the initial project. To run it you need:
Best regards.
Hi,
In Flux supervisor example, there is a tutorial about the DC motor. You can use it to create your own Dc motor.
