spiral inductor hfss

I need HFSS spiral inductor example,I'm learning HFSS by myself.
But I don't know how to set boundary and port.
Does anyone have ?

thanks

You can find under 'draw' a user defined primitive that is a square coil.I put a ground (GND) plane under the coil, assigning it the property of PEC to it and then connected the GND to the coil by a cylinder of some conducting material. I draw a rectangle between the other extremity of the coil and the GND assigned it a lumped source. To view the far field you can draw a rectangle sorrounding the structure and assigning it the boundary 'radiation'. I hope it's something useful to you

Added after 48 minutes:

sorry I mean sorrounding it by a box...

thanks for your feedback.
could you pls send your HFSS project to me ?
I am designing a planr spiral inductor on Silicon substrate.
How to setup the dielectric material between spiral inductor and its underpass ?

I always meet this mistake

There is one good example in Chapter 10 of HFSS fullbook v10.0.

I'm uploading the file, but I think it's very basic. Bye!
