Re: NEC-LIST: How can I use the currents in the out files ot compute far filed?

Assuming you don't just run your model with one element at a time, and that
you want to include the effects of mutual coupling?

That is, you want to look at the far field contribution of each element,
counting those contributions from adjacent elements which have currents from
mutual coupling? For this you just short/load the feedpoint of the other
elements, then run the model with only one element excited, and get the far
field.

If you're thinking about running the model, then manually summing the
farfield contributions only of the currents in one element (and neglecting
the currents in the other elements), where some of that current is the
result of coupling from adjacent elements, that's a bit more of a challenge.
(I can see wanting to do this if you are trying to model a small chunk of a
large array, and you want the element pattern to multiply by the array
pattern of the larger array)
