Hi Experts ,I’m just start studing Julia. But I’m in truble. Berrow 2D turblence simulation code is that I translated from Matlab. But It is not working well, very slow and use a lot of memory so I couldn’t run 3D version. I would like to borrow your help. using FFTW using Printf using LinearAl…

How I can change script for speed up

don’t roll your own rk4. use an integrated from DifferentialEquations.jl
