Multifragmentation is observed with an improved Boltzmann-Uehling-Uhlenbeck model for {sup 40}Ar+{sup 51}V and {sup 92}Mo+{sup 92}Mo collisions. For {sup 12}C induced reactions, however, a single residue is observed up to energy {ital E}/{ital A}{approx}200 MeV. By investigating the dependence on the masses of the projectile and target and on the equation of state, we demonstrate that the dynamics of compression and expansion, rather than the thermal excitation energy, plays the dominant role in causing the observed multifragmentation.
