You can plot Power Spectrum. Go to Plot/FFT. Then choose the file and type of plot that you want.

where is the second peak? is it twice the St #. Well first is this sprectrum for Cl or Cd. There is meant to be a second peak in the Cd spectrum, and the Cl should just have one at the St. Hope this helps.

is this and isolated cylinder or on near a wall or object??
