FFt of time domain fields in HFSS

[PacoKreiosSpace]

Hello everyone,

I am trying to convert the time domain fields plotted in HFSS transient into frequency domain with an FFT. I know thta I can visualise spectral data in a report (such as the S11) but I cannot do this in the fields visualisation. has anyone tried to do the same inside the software and managed to do it? If not, I know that there is this example https://examples.aedt.docs.pyansys.com/version/dev/examples/high_frequency/antenna/large_scenarios/time_domain.html which does the iFFT of the frequency domain fields of an example. Would someone know how to do it for another project that is not the one in the example?

Thanks in advance, if something is not clear please let me know and I can try to rephrase it!

Best regards,
Paco.
