COMPUTER CODES DEVELOPED BY DR. CLEMENT AND HIS STUDENTS

**SITE IS UNDER CONSTRUCTION.**

Please read this section before downloading codes from this website
As part of various research efforts, my students and I have developed several computer tools over the past 25 years.  I believe in free exchange of knowledge in all areas of society and that knowledge should be disseminated and shared freely.  Therefore, I have started to post some the old source codes and their manual/write-ups as I find them.  You are welcome to use them in any way you want, but not for commercial purposes.   Any modified versions of these free software tools should cite the original work and the derived work should also be distributed as a free open source code as well.  If you are not supportive of this idea, please don't download or use these codes.  Also, email mail me if you found any of these tools to be useful in your research; it is incredibly satisfying to see our work being used by others. Please note some of these tools are really, really old and I may not be able to provide any support; you are on your own and use them at your own risk.

I have also posted several useful codes and lectures at my modeling course website: http://www.eng.auburn.edu/~clemept/Numerical_methods/NumericalMethodsHomePage.html
