We keep seeing wiggles in our time- and plane-averaged profile for the turbulent dissipation rate \epsilon obtained from Nektar++ DNS results, as shown in the attached plot. They seem to appear whenever calculating profiles of second or higher order flow statistics involving velocity gradients, whereas the time-averaged flow profiles themselves look alright. From earlier posts, it seems that similar issues have also been reported by other users. Is there a way to alleviate the issue either through adapting the simulation or the postprocessing procedure, i.e. smoothing? Best regards, Cheng
