Confined Hard Disk System Model 

written by Wolfgang Christian

The Confined Hard Disk System is an idealized statistical mechanics model that simulates a two-dimensional system of hard disks confined to a box with a constant temperature thermal reservoir at one end and a movable piston at the other.  Slow-moving particles are color-coded as blue and fast particles are color-coded as yellow.  The model computes and plots the time evolution of the kinetic energy K per particle, the pressure P, and the volume V.  The model also displays histograms and mean values of these quantities.

The Confined Hard Disk System was created using the Easy Java Simulations (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the  ejs_stp_hd_ConfinedHardDiskSystem.jar file will run the program if Java is installed.
