Thanks for pancho_hideboo's replying!
I am new with HFSS, so i don't quite understand the settings such as boundarier and terminals in HFSS.

Just Poly Layer isn't used in inductors of examples you saw, is it ?
Yes, poly layer was not used in inductors of the example I mentioned. So, the poly layer should be omitted in the model due to its absence in the inductor structure?

Is there any relation with Poly Layer ?
If your process have only two metal and one poly, you have to use poly layer as shield layer.
There are 1 poly layer and 6 metal layers in the process i use, and i use the metals as floating shield layers rather than the poly.
I actually want to know whether HFSS would take the shield layers into account when analyzing when these shield layers is "floating", that is, they aren't connected to any terminals or "ground" and they are not connected to the spiral inductor.
Furthermore, the floating shield layers are used to limit the effect from eddy current formed in the substrate. Can HFSS take the eddy current into account during calculation by default? If it can't, how should i do?
