Metropolis Monte Carlo and Creutz's Demon MD Model 

written by Fernando Silva Fernandes

The Molecular Dynamics, Metropolis Monte Carlo and Creutz's Demon Model compares canonical molecular dynamics and Monte Carlo versus microcanonical Creutz's demon simulations. The molecules interact in 3D through Lennard-Jones's potential and a wide range of densities, temperatures and energies can be simulated. The Monte Carlo computations sample the configuration and velocity spaces similarly to molecular dynamics. Thermodynamic properties, radial, speed and demon distribution functions are displayed allowing to assess the consistency between the ensembles and methods implemented. .

The Molecular Dynamics, Metropolis Monte Carlo and Creutz's Demon Model was developed using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.   Double clicking the jar file will run the program if Java is installed.  You can modify this simulation if you have EJS installed by right-clicking within the map and selecting "Open Ejs Model" from the pop-up menu item.
