I wrote a small Lua script to generate a Fast Henry input file. I then discretized a circular wire (using LuaMath and then created an input file with all the segments. The repository for the utils and the code is here
The obtained inductance matches the inductance calculated for a circular wire using the inductance expression as given here
the skin effect also shows up because I see the resistance increasing with frequency and the inductance falling somewhat.
When i removed the .equiv statements which was making all the starting nodes of all the segments of the same potential the inductance changed a little bit not much but the skin effect was lost.
