Molecules is a two-dimensional molecular dynamics simulation for Windows or Mac
Thermal Physics software for Mac and Windows
* Molecules is a two-dimensional molecular dynamics simulation, similar to the Molecular Dynamics applet. This version has somewhat different features including the ability to simulate two types of dissimilar particles. The program is available for several platforms:
o Mac OS 8-9. Also runs in the Classic environment under OS X. (.sit format, 792k).
o 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 better performance and smoother animation (though with some flicker). (.sit format, 975k).
o Windows 95 or better.
o REALbasic project source file. (.sit format, 143k).
o Source code in plain text format (61k; possibly useful if you want to see the algorithms or port the program).
o This software is issued under the GNU General Public License, which you should read if you intend to modify or distribute the program.
