Eddy Currents in 3-D

I am analysing the effects of a magnetic core in a winding at high frequency. To do so, first I'm comparing 2-D and 3-D simulations, as the 3-D simulation should calculate more precisely the Eddy currents in this magnetic core, comparing the impedance of the conductor.

As I read in the literature, using complex permeability for the material in 2-D will give the same impedance results that in 3-D, but when I simulate the three options, the 3-D gets a lower impedance than the other two.

I Flux doesn't let me solve the problem unless I put an electric loop cut in the iron sheet, can this be the cause of the miscalculation?

I attach the 3-D simulation.

Thank you

    Hello Yerai,

    Could you better explain the problem?

    What are you comparing exactly?


    The external core has a total height equal to 0.1 mm and it has a rectangular shape; this geometry seems to be not adapt for 2D model. Could you share the 2D model?


    The best way to proceed could be create a new ticket in the support section and arrange a meeting to better understand the problem.

    Regards,

    Thank you, I will create that ticket in support.
