Resumo
We carry out a study of the two-dimensional Blume-Capel model using the Wang-Landau Monte Carlo
method which estimates the density of states g E directly. This work validates the applicability of this method
to multiparametric systems, since only one computer run is needed for all range of macroscopic parameters
temperature, anisotropy, etc. . The location of the tricritical point is determined as kBTt /J=0.609 3 , Dt /J
=1.966 2 and is in excellent agreement with previous estimates. The free energy and the entropy, which are
not directly accessible by conventional Monte Carlo simulations, are obtained simply using g E .
