Xnec2c is a high-performance multi-threaded electromagnetic simulation package to model antenna near- and far-field radiation patterns for Linux and UNIX operating systems.
[ while using xnec2c-optimize ]
I found that xnec2c did not automatically re-run the frequency loop when
examples/yagi.nec was updated. I had to manually click the loop "play"
button to regenerate yagi.csv -- even though xnec2c is configured to
"Reload and write changes on .NEC file changes". Whereas,
xnec2c-optimize.pl does automatically detect .csv file changes.
I think I may have found the reason why. xnec2c's frequency loop only gets
re-run automatically when xnec2c's "Frequency Data Plots" window is open.
From an xnec2c perspective, there is only a single frequency selected unless the frequency plots window is open. If it is open then it sweeps, but if it is closed it only calculates the selected frequency.
TODO: Maybe xnec2c can be configured to sweep if freqplots is open, or maybe just have it open freqplots automatically and click "play" when optimization is selected.
