Hello, thanks for the bug report.

I don't know anything about antenna design or anything that this software is
doing, so I might have to ask you to simplify a bit. As far as I can tell there
are two different bugs you're seeing:

1. one or more calculations done by the program produces slightly inaccurate
results under Wine,

2. the radiation pattern plot doesn't appear.

(1) is tricky, because Wine does little to no math itself, instead relying on
the host C library. Presumably the code is calling into some C library, and
there are some floating point inaccuracies? The first thing I'd try is to
replace that C library with the native version to see if that is indeed the
problem, but first we need to know which one it is. Can you attach a log when
running the program (and doing whatever actions lead to this inaccuracy being
visible) with WINEDEBUG=+loaddll?

(2) I may need more information for. Is this potentially a graphical failure?
e.g. is the plot blank, or are there axes or something similar but no data?
Screenshots may be helpful here.
