zero induced current density at conductor boundary, is this normal?

I'm modeling a coil-over-steel-plate system using 2D Perpendicular Induction Currents, Vector Potential mode (emqa), time harmonic analysis (f=1.0 MHz).
The calculated induced current density Jz at the plate surface (please see the attached picture) is exactly 0. However, 0.001 mm into the plate will give a induced current density of the order of 10^8 [A/m^2].
Why am I getting zero induced current density at conductor boundary? I checked the 2D eddy current model in the model library (axi-symmetric mode), the induced current density at conductor boundary is not zero and is continuous to its inside values.
Any hint will be greatly appreciated!
