Non-linear responses of the hard-spheroid fluid under shear flow

We examine a simple non-equilibrium molecular dynamics (NEMD) technique for studying hard-spheroid fluids under shear flow. The method involves applying a thermostat which uses an analytical formula for the streaming angular velocity as a function of molecular orientation. Preliminary results indicate that this method is a significant improvement over the usual assumption of constant streaming angular velocity. We compare with the more sophisticated, and complicated, rotationally unbiased thermostat proposed by Travis et al.
