Molecular Dynamics Demonstration Model
written by
Wolfgang Christian
The EJS Molecular Dynamics Demonstration model is constructed using the Lennard-Jones potential truncated at a distance of 3 molecular diameters. The motion of the molecules is governed by Newton's laws, approximated using the Verlet algorithm with the indicated Time step. For sufficiently small time steps dt, the system's total energy should be approximately conserved. Users can select various initial configurations using the drop down menu.
Ejs Molecular Dynamics Demonstration model was developed using the Easy Java Simulations (Ejs) modeling tool based on a Java applet written by Dan Schroeder, Physics Department, Weber State University. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the js_stp_md_MolecularDynamicsDemo.jar file will run the program if Java is installed. Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models. Additional Ejs models for statistical mechanics are available. They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs. Please note that this resource requires at least version 1.5 of Java.
