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

How to start up? Initial configuration: Criteria for choosing initial configuration: quick relaxation to the equilibrium state. Random initial configuration: Advantage: liquid-like, easy to generate. Drawback: substantial overlaps at high densities. Use: Monte-Carlo for systems without hard-core interactions. Not suitable for hard-core interactions and MD at high densities
