Fast Euler and Navier-Stokes fluid flow simulation

version 1.0 (4.3 KB) by

Three m-files to realize easily simulations of fluid flow in a rectangular cavity.

Here are two examples of videos:

The colors show the vorticity of the flow.
Enter the command line:
where L and l are the width and height of the box containing the fluid and lambda_max is an integer that will be used to determine the number of degrees of freedom (the larger it is, the better the simulation will be but the longer the computation will last). As a first guess, you can try : l = 4, L = 3 and lambda_max = 60.
Once the computation is done, enter:
film = graph_flow_euler
to make a Matlab movie.

how to compile it?

It works and the results are beautiful, but I've no idea what I'm looking at. Some description please!
