Getting very low flux linkage in ANSYS Maxwell

Click For Summary
SUMMARY

The discussion centers on low flux linkage results encountered while using ANSYS Maxwell for inductance calculations. The user, Tom, inquires about potential causes for the low flux values despite obtaining close inductance results. Key advice includes verifying the core construction, specifically the material and positioning of the bottom bar of the core, as referenced on page 5.2-7 of the user's guide. Ensuring these factors are correct is crucial for accurate flux linkage outcomes.

I'm new to ANSYS Maxwell and I'm trying to follow the inductance calculation example in the user's guide.
The results for the inductance are pretty close but the value of flux are very low. What cause this? What should I do?

I've never used Maxwell, but check the core construction. Particularly is the bottom bar of the core both the correct material and in the correct position? See pg 5.2-7, and surrounding, of your attached PDF.

Cheers,
Tom

Thank you Tom.
I've checked and I think that the material and dimensions of the model are correct.
