Hi.

Now, I am modeling simply transformer in 2D.

I wanna determine the induced current of secondry wire.

I used the Comsol Sover which is AC/DC Module -> Quasi-Statics, Magnetic -> Perpendicular Induction Currents, Vector Potential -> Time-harmonic analysis

Expecting a response to this question

I'm not sure this can be done in 2D. Real-world transformers have closed and finite current loops. Your choice of applications has currents only perpendicular to the plane of the computation, and of infinite extent (in/out of the plane) But you would have other issues in the in-plane currents application anyway. I suppose if you don't have enough memory for a good 3D model, you could model parallel current rings in axial-symmetry 2D mode.

Anyway, what is the geometry of the transformer you are trying to model?
