nasir.iitd Member SHEIKH NASIRUDDIN Join Date: Aug 2013 Location: DELHI Posts: 52 Rep Power: 13	Hi everybody, I'm having fluent temporal data(LES) at every time step. In fluent we can plot Power density spectrum(y-axis) versus frequency(x-axis). But I want to plot Energy spectrum (y-axis) versus wavenumber(x-axis). Can any help how to do it ? Any help will be highly appreciated.
