  We have undertaken a large set of simulations of galaxy interactions and
mergers (GalMer Project) in order to study the physical processes related to
galaxy encounters. All morphological types along the Hubble sequence are
considered in the initial conditions of the two colliding galaxies, with
varying bulge-to-disk ratios and gas mass fractions. Different types of orbits
are simulated, direct and retrograde, according to the initial relative energy
and impact parameter. The self gravity of stars, gas and dark matter is taken
into account through a tree-code algorithm, the gas hydrodynamics through SPH.
Star formation is included adopting a density-dependent Schmidt law. This wide
library of galaxy interactions and mergers, containing, at present, about 900
simulations of major encounters, represents an unique tool to investigate
statistically the chemodynamical evolution of interacting systems. In the
following, we present and discuss some results obtained exploring the dataset,
together with some future perspectives.
