How to get Fourier spectrum (complex number Real+imag) in Harmonic analysis

    • JHKim


      I am trying to get frequency response function(FRF) in Harmonic analysis.

      I can export Amplitude and Phase angle at Tabular Data from Frequency Response(Acceleration),

      but I want to get Fourier spectrum data that should be complex domain format(Real part +imaginary part)

      I cannot find how to get complex domain format in Harmonic analysis

      How can I get it ???

      Not sure how to do that in workbench -


      In general for complex numbers though we have the phase (phi) and amplitude F - then the real part is


      Real = F*cos(phi)


      and imaginary is:
