  1. Hi, I have carried out PSD analysis in Ansys APDL. I want to do post processing in HyperView/HyperGraph. Contours of Stress, Displacement and Acceleration were plotted successfully by reading suitable Load steps. But i could not generate Response PSD curve at the required node location. However i tried converting random vibration curve(displacement vs frequency to acceleration vs frequency) and then convert it to PSD curve using math operation in HyperGraph. But this has been one hard nut to crush so far. Please suggest me the suitable tutorials on using PSD math operation in HyperGraph. Thanks in Advance....
