  I am using Q3D in ANSYSEM to calculate the inductance and ESR of my coil in wireless power transfer system. This is the coil I am using. Now I want to replace the wire I am using with litz wire and explore the influence of proximity and skin effect on ESR but I don't know how to draw litz wire.
  
  I drew the coil with Draw>User Defined Primitive>SegmentedHelix>PolygonHelix

  Litz wire cannot be simulated in Q3D.
  
  In Maxwell 2D/3D 2019R3, you will be able to solve with Litz wire in the transient solver only. Litz wire in the 2D/3D Maxwell Eddy Current solvers is planned for 2020R1.

  I noticed in the menu, there is an item called PEmag and I found Litz wire in there. Can I use that to simulate Litz wire? If yes, how can I do that.

  Hi mchristi,
  
  Could you detail more how Litz wire can be used?
  
  I know you can select the material composition as Litz wire. After that, all the setup is exactly the same taht for a solid wire? The current distribution on the wire will be show?
  
  Thanks

  Hi mchristi,nCan you explain how the Litz wire is modeled in Maxwell? I mean I know how to use it and how to run the simulation, but I don't know how Ansys modeled a simple copper conductor as Litz wire.nIs it modeled using equivalent complex permeability as described here https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=4802255?nThanksn
