The lattice Boltzmann method in 25 lines of MATLAB code (LBM)
When "LBM_25_LINES.m" is started, the LBM solves the flow field in a "pseudo-porous" geometry with periodic boundary condition. A perturbation to the velocity field in the x-direction is applied so that the flow moves from the left to the right side of the computational domain.
When "LBM_VIEW.m" is started, the m-file script shows all LBM process at the mesoscopic level. At each time step, the collision, the bounce-back and the streaming step are showed with details and at the same time the macroscopic velocity field is plotted.
Note that these two m-files are not research code! Although, they might be use as a starting point.
Overall, I believe that these two m-files may be of a good addition for a general audience scientific presentation.
Enjoy!
