The Miesowicz viscosities ${\mathrm{\ensuremath{\eta}}}_{1}$, ${\mathrm{\ensuremath{\eta}}}_{2}$, and ${\mathrm{\ensuremath{\eta}}}_{3}$ and the Leslie coefficients ${\ensuremath{\gamma}}_{1}$ and ${\ensuremath{\gamma}}_{2}$ of perfectly aligned nematics are determined by nonequilibrium molecular-dynamics simulations. The results are compared with theoretical predictions and with experimental data.
