A manual outlining the purpose, model, and simplifications used in this program is available here.


Computer Platform:

The software is written in Java and runs as a stand-alone application or as a Java Web Start package. We recommend using the Web Start version. The Java  run-time package and Web Start software are  available free of charge from Sun Microsystems, Inc. The program was developed and tested on various Windows platforms as well as on Linux and MacOS X. We recommend 256 MB or more of Random Access Memory. Approximately 40 MB of disk space is required. 


Link for Java Software:

Before a Java Web Start program can be used on a computer, the supporting software must be installed. This is needed only 1 time per computer no matter how many different applications use it. This software was tested using the Java 5.0 Run Time Environment. Sun Microsystems Inc provides this package free of charge at http://java.sun.com/ or it can be downloaded here for computers running Microsoft Windows. If this is the first time you are using it, just download the file from the site above. Follow the instructions given there for installations. I recommend that you accept the default values proposed in the install process. 

Download/Execute Program:
