Sažetak
The exact solutions of the hard-disk collisions obeying Sllod dynamics (so named because of its close relationship to the Dolls tensor algorithm) with isoenergetic and isokinetic constraints have been presented and discussed. In equilibrium the trajectories in the isokinetic and isoenergetic systems are indistinguishable, but the pressures are not equal. Outside equilibrium, with a shear present, the isoenergetic constraint is shown to be inappropriate for the Lorentz model. The solution of the isokinetic hard-disk collision has been used to evaluate and qualitatively explain the dependence of the potential part of the pressure tensor on shear rate. The hard-disk results have been compared to the results for soft disks.
