  Hello
  
  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:
  
  Imag=F*sin(phi)
