This is one of our toy projects aimed at illustrating phase transitions, and other phenomena at a microscopic level by means of Molecular Dynamics for educational purposes. This program performs an MD run with 2D particles interacting via tunable soft potentials (from repulsive WCA to LJ) for symmetric binary and ternary mixtures, with and without walls and gravity. Click here to view a detailed description of the program or here to download the PDF documentation.

The visualization and interface code is programmed in Java and the Molecular Dynamics in Fortran 90 interfaced using Java Native Interface. It is a standalone application tested both on Linux and Windows platforms. Porting to other platforms for which Java is available should be straightforward.

The program is available from the authors upon request for Linux and Windows (2000, XP or 2003). Write to Esta dirección de correo electrónico está siendo protegida contra los robots de spam.

Click on the picture below to view an online demo with reduced capabilities (it runs a pure Java applet vs. the standalone version that uses precompiled optimized Fortran binary libraries). Warning : DO NOT start more than one copy of the applet simultaneously using the same browser.
