Frequency loop not ran with --optimize and a single frequency specified

[malcolmboyd]

Hello,

I have not been able to get the frequency loop to run with the --optimize flag on and when specifying a single frequency. I do get a radiation pattern output when I manually open the file in the editor and click save though this doesn't appear to output the csv file required for optimizing.

Command to open xnec2c:

xnec2c -j 16 --optimize -i output/antenna.nec --write-csv output/antenna.csv

Input file (output/antenna.nec):

CM Curtain antenna

Interesting, does not work with more than one frequency?

if so then there is some kind of edge case that is missing for optimization ...
