Hi John,

This CFD “solver” is only a toy solver that we intend to use as a basis for a Julia lecture (just like I did with my toy 2D Shape collisionner [Plot a circle with a given radius with Plots.jl - #8 by LaurentPlagne](https://discourse.julialang.org/t/plot-a-circle-with-a-given-radius-with-plots-jl/23295/8)

I have translated the famous [mit18086](http://math.mit.edu/~gs/cse/codes/mit18086_navierstokes.pdf) from Matlab to Julia and replaced the cholmod solver by an home made geometric multigrid solver (that must be able to solve full neumann B.C.) translated from C++ to Jula.

The resulting Julia code is reasonably fast (5-100 times faster than the matlab original code depending on the mesh size)

For your question, I dot not use the classical post-processing workflow and the Makie plots are computed and displayed during the simulation (and the movie being recorded live) but I do not emit a frame by timestep: there is about 20k \Delta t and around 200 frames 😉

I agree that visualization during simulation is rather convenient and do this only with Julia is very nice !
