The Lattice Boltzmann Method is based on a somewhat strange discretization – we discretize time and space as usual onto a lattice with fixed width steps, and we discretize velocity into a finite number of potential directions. The lattice can therefore be generated by three unit vectors, a 1, a 2 and a 3 and a set of integers k, l and m so that each lattice point, identified by a vector r, can be obtained from: r = k a 1 + l a 2 + m a 3.
