STP Lennard-Jones 2D MD Program
written by Harvey Gould, Jan Tobochnik, Wolfgang Christian, and Anne Cox
The STP LJ2DMD program is a molecular dynamics simulation of a system of particles in two dimensions interacting via the Lennard-Jones potential. The default initial condition is an array of N=64 particles of diameter 1 in a box of length L = 18 and an initial kinetic energy per particle of 1.0. Additional states and parameters can be specified using the Display|Switch GUI menu item.
The program is distributed as a ready-to-run (compiled) Java archive. Double-clicking the stp_LJ2DMD.jar file will run the program if Java is installed on your computer. Additional programs can be found by searching ComPADRE for Open Source Physics, STP, or Statistical and Thermal Physics.
Please note that this resource requires at least version 1.5 of Java.
