This work was part of my Ph.D. thesis work in Indian Statistical Institute, Calcutta (Kolkatta). At that time it ran on VAX systems with 512MB RAM! Dr.U.N.Sinha, developed his FloSolver in 1986, a powerful super computer for such flow simulations. Now I am able to run this on my laptop with 12th generation Intel 5 and 12 CPU cores using OpenMP support!

We use FORTRAN for generating flow data and Lua-Love2D for displaying results as a graphical simulation. Rewriting the FORTRAN code in Mojo to see how fast it runs on my laptop. Also hoping to do some Deep Learning simulations of vorticity flows with some application to ocean and atmospheric flows.

For boundaryless free flow:

cd free2d/
./free_vortices2d.sh
0

Please supply '0' as input as it waits to receive it. If you have alreday run till 25 iterations then you can restart from 25. The output is written to free2d/out/ folder.

For 2D channel flow:

cd channel2d/
./channel_vortices2d.sh
0

Please supply '0' as input as it waits to receive it. If you have alreday run till 25 iterations then you can restart from 25. The output is written to channel2d/outc/ folder.

Install Lua and Love2d

For boundaryless free flow:

love free2d/ free2d/out/

Sample 1: free vortices video

For 2D channel flow:

love channel2d/ channel2d/out/

You should here sound of water flowing!

If you are Windows user you should be able to modify the shell script to a batch script and run it on Windows. Lua-Love2d also should run fine on Windows! Please do tell me if you have difficulties running on Windows!
