PCB meshing for planar transformers

  I am simulating a planar transformer in Ansys Electronics using a 3D AC magnetic simulation. The winding loss results are not accurate, mainly because the mesh is not fine enough across the copper traces. I have tried several approaches but have been unable to obtain accurate results. The simulation frequency is a few hundred kHz.
  Is there a way to control the mesh density independently along different axes? What would you recommend?

  For better mesh refinement, you can use additional Mesh Operations: Length based Mesh Refinement, “Skin Depth Based” Mesh Refinement. Or manual slicing the copper into thin layers.

    Length-based meshing was not effective because my model's dimension in the Z-direction is much smaller than its dimensions in the XY plane. Skin-depth refinement also did not help significantly. Are there any other methods to apply anisotropic length-based meshing in eddy current simulations, similar to what is possible in Icepack?
