I have been working since many year with Nec2, 3 and 4 in computing
transient response of metallic structures. For that, I have developed
small FORTRAN programs to generate normalised "double exponential" and
all kind of transients. I have never worked with "Win NEC Pro", but if
this program permitted to access to an output file like Nec, I think
that it would be easy to use this output file to generate the transfer
function of your system in function of the frequency. When this is
done, the rest will be easy as the programs I have developed will
compute the Fourrier transform of the excitation, then will multiply
it by the transfer function given by your program and convert the
result back in the time domain very easily for all the segments or
some of the segment.
