  Selected results of a classical simulation of N bodies in strong interaction
are presented. The static properties of such classical systems are
qualitatively similar to the known properties of atomic nuclei. The simulations
of collisions show that all observed reaction mechanisms in nucleus-nucleus
collisions are present in this numerical simulation. The first studies of such
collisions are in qualitative agreement with experimental observations. This
simulation could shed a new light on energy deposit in heavy ion collisions:
the excitation energy of each cluster is found lower than the energy of the
less bound body in the cluster. Finally, the similarities of fragmentation
pattern with those obtained with a statistical code indicate that an
unambiguous link can be established between the statistical and the dynamical
descriptions of reaction mechanisms.
