title: Computer simulations of complex chemical systems.
abstract: In this paper, after a brief description on our approach to simulations of chemical systems, some of the results obtained are discussed. Four examples are reported: 1) liquid water simulation which takes in account a four-body potential; 2) hydration networks in a crystal; 3) water and ion structures in DNA; 4) proton tunneling in DNA base pairs. We include also a short description of a parallel system we have assembled.
