Cool packages: lammps

Lammps is a molecular structure simulator package for Unix. I first heard of lammps when I was looking for a tool for my science project about viscosity and molecular structure. Anyway, the lammps site is http://lammps.sandia.gov/. The package must be compiled from source. For information on this and compiling lammps, go here: http://lammps.sandia.gov/doc/Manual.html. This will explain compiling the package source and editing Makefile.foo, where foo is your platform. Hopefully this package will prove useful to some of you.
