    • In the original equations epsilon is taken to be 1 -ẽ. Since the energy dissipated in a single collision is proportional to $1 -&etilde2, on the average, we prefer to choose ε = 1 -&etilde2.

    • The initial condition is prepared in two steps. First a random generator is used to assign the particles random positions (in the rectangle) and random velocities whose distribution is Maxwellian. The next step consists of performing a run in which the collisions are taken to be elastic for about 100 collisions per particle to ensure an initial equilibrium state (uniformity of density is then tested by computing the time average of the density in each of the 32 times 32 cells, cf. text; the isotropy and Maxwellian nature of the initial condition was tested in a similar way as well).
