Maybe use J=σE. Get the E from the cross section and multiply by the sigma.

You can take a look at ex22
. It only needs some minor modifications to get exactly what you need.

Thank you for your help,
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.
Thank you again,

I succeeded, you can close the issue.
