I looked at the examples but I do not find any that compute the current density distribution in a wire according to frequency. When AC current circulate in a wire, the current has a tendency to concentrate on the perimeter of the wire, this is the skin effect. My goal is to use a 2D section of the wire and compute the current density distribution for various frequencies and then of various section shapes.
Is there an example that I can start from? If not can I have some guidance?
Thank you,
Denis

In the heading comments of ex22 it is written: "In each case the field is driven by a forced oscillation, with angular frequency omega, imposed at the boundary or a portion of the boundary."
This sentence seems to implied ex22 is simulating in time and the boundary are driven by a sine wave. In the code the boundary are set to 1. I am confused.
For skin effect I was expecting the boundary be fix as example 1 for the current density.
I deducted the equation for the current density in 2D (div grad Jz - i w mu sigma Jz + w^2 eps mu Jz = 0) and it look like problem 1 (case 0), so I will start from there.
