Hi, 

I am getting started to maxwell via the learning hub. In the lectures, I came across the fact that BP curves have to be fed at different frequencies for core loss prediction. 

Getting BP at high frequencies is challenging, but loss tangent with lower excitation strenghts can be obtained. I used the pwl command to input my frequency dependent loss tangent - but however I don't see a value for the core loss in the solution data. Please let me know if I am missing something here -  in terms of GUI, or fundamentally. Is there any other option/formulae in the fields calculator that I can use to get the core loss? 

Appreciate your time, folks

Hello Sai,

      First, when using either single or multiple BP curves, Maxwell will extract core loss equation for the core loss calculation for any frequency. 

      When using "magnetic loss tangent", you have to use field calculator to integrate EM_loss on the objects to get this core loss. Thanks.

Hi, 

The cyliner is the torroid. I have taken the volume average of the EM_loss, and I am getting weirdly high values. Since fields calculator always displays in SI units, is this in W? Let me know if I am missing something - I can share more information about my model if needed.
