Implementation of a D2Q9 Lattice-Boltzmann simulator, and various experiments with it. Comprises the code portion of a final submission for the High Performance Computing with Python course.

Our results can be reproduced in full by executing msub.sh, and then plotted using plots.sh.

All the computation code can be run in parallel with arbitrary lattice sizes, numbers of processors, and processor grid layouts. (Note: plotting code in plots.sh and *_plots.py should only be run in serial.)

Command line argument for the non-plotting python scripts are:

    --lat_x, --lat_y : int
        overrides default x- and y-dimensions of the entire lattice

    --grid_x, --grid_y : int
        overrides default x- and y-dimensions of the cartesian processor arrangement. 
        If specified, their product must match the number of processors in use.
