How to analyse the errors of simulation results? Sustematic errors: Possible sources. 'poor equilibration; bad random number generator; 'system size effect. Practical method for detecting systematic errors: -longer simulation, different initial configurations; test random number generator, use different generators; simulation with larger systems

Molecular dynamics for continuous potentials Short history: The first MD simulation for a system interacting with a continuous potential (Lennard-Jones potential) was carried out by A. Rahman in1964. A. Rahman, Phys. Rev. 136, A405, (1964). Main differences between MD with continuous poentials and
