Magnetic and Electric fields for coil coated with an electrically conductive material (two materials for coil)

Please login with a confirmed email address before reporting spam

Dear Comsol Community,

My objective is to observe the resonance for an inductor (coil thickness in range of micrometers) coated with a very thin electrically conductive material (1-2 um thick). I have generated a 2D axymmetric model for this purpose. I can easily simulate the resonance of the inductor alone (without the coating) with Magnetic and Electric fields (MEF) interface.

However, when I add another material on the surface of the inductor, an error is generated pertaining to the electric potential, an undefined variable - comp1.V. When I just use the Magnetic fields interface, there's no such error. As I see to it, the RLC coil group in the MEF interface computes the electric potential difference between the coil turns and assumes the potential to be the same across the coil cross-section, which isn't true in my case, as I have two materials associated on the coil domain. Is there any solution to modeling these thin domains surrounding the coils? I have attached the .mph file and generated error for your reference. Any help would be appreciated.

Cheers, Saoni
