Plotting streamlines

You may take a look at Makie streamplots :

Asynchronous Makie

For @tyfdzt: here are the basic components extracted from my code with Makie streamplots. Note that it is not a MWE. I hope it can help you. If not I can try to write a MWE. #The Cartesian axis : x = range(0,stop=lx,length=nx+1); hx = lx/nx; y = range(0,stop=ly,length=ny+1); hy = ly/ny; #Arrays for x and y velocity arrays that evolve via CFD simulation Ue=zeros(nx+2,ny+2) Ve=zeros(nx+2,ny+2) ..... #Declare a Makie Node (once) for storing velocity arrays uvn=Node([rand(size(Ue)...),rand(size(Ve…
