- Does anyone know this problem about the molecular dynamic program for a
- pure hard sphere fluid. This reads input positions and velovities from
- a file, and after simulation it writes out the final positions and
- velocities to a data file(Config). When changing from one state to
- another, it is necessary to equilibrate the configuration at the new
- state before collecting data for final statistical analysis. First,
- choose a reduced density between 0.0 and 0.943. Beginning with 100
- collisions, see how the final value of PV/NKT - 1 approaches an
- equilibrated value by running again and again and using the utput in
- CONFN as input for the next run; once equilibration is attained there
- will be statistical fluctuations but no trend. How many collisions were
- needed to reach equilibrium? How many collision did you use to obtain an
- correct averaged value of PV/NKT - 1?

- If you can solve to this problem, I deeply appreciate you.
