Flux PEEC - Litz coil

Hello, everyone

I recently started using the PEEC method inside Flux and I would like to know what is the best way (if possible) to model or import a coil composed by Litz wires.

Thank you.

    Hello;

     

    can you please tell us why you want to model all the wires ?

    If it is to see if there are additionnal losses, may be it is better to use Flux in AC Steady state application. There is homogenized coil conductor region, where it is only needed, to indicate the wire size, number of wires in one direction, and number of wires in the perpendicular direction. You can then make a study depending on the frequency and plot the losses vs Frequency later.

    Hello,


    I've been conducting a comparison experiment on a WPT system. The PEEC would be useful for simulating with a metamaterial and it would be important to keep the coil properties from the previous FEM simulation, modeled with Litz wires to reduce skin effect losses.

    Hello,

    I agree with Farid, Flux in steady state with "coil with losses" model should be better than representing each wire individually in PEEC.

    Also depending on the shape, PEEC could be unadapted (rounded or circular shapes would not be ideal)
