Employing an extended version of the Boltzmann-Uehling-Uhlenbeck equation, we present simulations of the reaction 800 MeV/nucleon Ca+Ca. Deuteron spectra are calculated from the model without ad hoc assumptions. Absolute values of the proton and deuteron spectra are in good agreement with experiment. The dependence of the total deuteron yield on the nuclear equation of state is investigated and found to be weak. Both entropy and freeze-out density are strongly dependent on impact parameter. This suggests, in particular, that the freeze-out density has no physical meaning. Methods for calculating entropy are discussed and numerically compared.
