The STP FPU program simulates the Fermi-Pasta-Ulam problem of a chain of particles coupled by spring-like forces which are linear and cubic in the displacement of particles from their equilibrium positions. The problem was first simulated in 1953 by Enrico Fermi, John Pasta, and Stanislaw Ulam as a way to try to understand how a one-dimensional crystal evolves toward thermal equilibrium. The default system is a chain of N = 18 particles initially in the n=1 mode.
STP FPU is part of a suite of Open Source Physics programs that model aspects of Statistical and Thermal Physics (STP). The program is distributed as a ready-to-run (compiled) Java archive. Double clicking the stp_FPU.jar file will run the program is 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.
