Hi LNA,

Just dropping a quick question, when you had "small strange oscillations at the large wave numbers" i.e. that little weird peak, do you have data readily available to plot with that version of your code, I was hoping you could obtain this function just so I can confirm something im not seeing in my DNS, the function is;

E(kappa)*kappa^(5/3)/epsilon^(2/3)=C_kol

i.e. a plot of C_kol vs kappa*eta with logarithmic x and y axis, Its a compensated kolmogorov energy spectrum function

If you could upload a plot that would be awesome!!
Thanks in advance!
