Dear all, I am using the homplane FieldConvert module with the wavespace option , but I do not completely understand the output (fld) result. I have performed a quasi 3D simulation, with up to 3 Fourier modes (HomModesZ = 4). Then, I use the FieldConvert -m homplane:wavespace:planeid=<value> ... command to obtain the Fourier coefficients. I have extracted 4 different planes, i.e. value={0,1,2,3}. I would like to know what is the information contained in the fld output files. Does planeid=0 and planeid=1 correspond to the real and the imaginary parts, respectively, of the Fourier coefficient for the mode 0, and planeid=2 and planeid=3 correspond to the real and the imaginary parts, respectively, of the Fourier coefficient for the mode +-1? Thank you in advance. Regards, Guillermo
