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