Ising is a Monte Carlo simulation of the two-dimensional Ising model.

Ising is a Monte Carlo simulation of the two-dimensional Ising model, demonstrating phase transitions of a magnetic system. You can adjust the temperature, magnetic field, and lattice size (up to 400x400) while the simulation is running. Besides graphical output, the program keeps track of the current value, average, and standard deviation of the energy and magnetization, which you can copy and paste into a spreadsheet for further analysis. The current version of Ising is 1.1, posted 22 September 2002 (see source code for a list of changes since version 1.0). This program is available for several platforms:

    * Mac OS 8-9. Also runs in the Classic environment under OS X. (.sit format, 728k).
    * Mac OS X. Also runs under OS 9 with CarbonLib. Note that, due to the double-buffered graphics on OS X, the Classic version (above) gives slightly better performance and smoother animation in the "update continuously" mode. (.sit format, 910k).
    * Windows 95 or better. (.zip format, 473k).
    * REALbasic project source file.  (.sit format, 89k).
    * Source code in plain text format (32k; possibly useful if you want to see the algorithms or port the program).
    * This software is issued under the GNU General Public License, which you should read if you intend to modify or distribute the program.
    * There's also a stripped-down Java version of this program ...
