  We performed extensive molecular dynamics simulations to obtain
pressure-density phase diagram, orientational order parameter, pair correlation
functions and translational diffusion coefficients of Gay-Berne fluids.
Different sets of parameters were employed for the Gay-Berne potential, in
particular we studied the cases $\kappa'=5, 10, 15, 20$ and $\kappa=3$,
$\mu=2$, $\nu=1$ at different conditions of density and temperature. The
structure was analyzed in terms of the order parameter and the pair correlation
functions. We found that for the highest value $\kappa'=20$ the region where
pressure increases with density is significantly reduced at low temperatures;
additionally the pressure shows several decays with density as an indicative
that several structural phases can take place. These effects are discussed in
terms of the pair correlation functions. For higher temperatures the pressure
shows only two decays for all $\kappa'$'s studied. As this parameter increases
its value those decays are shifted to lower densities.
