[Nektar-users] Kinetic energy spectra

Dear Nektar users and team, I'm working on the correct "guess" to parameters SVVCutoffRatio and SVVDiffCoeff of the model SVV LES (SpectralVanishingViscosity). I trying to determine the influence of that values on the Kinetic energy spectra. So, I need to get the values of the Kinetic energy as a function of the k (where k = 1:NUMMODES). Using the filter "Modal energy" (user-guide 3.4.9) it is possible to obtain the integral over all the velocity not with of the modes k. It is possible but just with one-dimensional homogeneous expansion and I wanna plot the data on a general model. May anyone gives me a hand with this, any help is appreciated. Thanks in advance, --- Manuel Felipe Mejía De Alba.
