Hello byeongwoo yoo,

Here we have 2 issues:

1/ no results when you compute the Coupling Coef.

2/ an error message when you import a 3D Component model.

I would start fixing issue number 2, since it could be related to issue number 1. The error message about the 3D component is very clear, you should use Eddy Current or Transient solver.

Looks like you are using the Magnetostatic solver. This solver only considers DC currents. If you are designing a WPT system, I would suggest using Eddy Current or Transient solver to capture the eddy currents on the metal sheet. Probably the usage of one of these solvers will also help to fix issue number 1.

I hope this helps. Ivonne
