__NOTOC__{{sitestatus}}[[Image:Main-screenshot.png|thumb|right|305px|The main window of the [[PyGTK GUI]] for ASCEND. There are [[PyGTK Screenshots|more screenshots]].]] ASCEND is an free open-source software program for solving small to very large mathematical models. ASCEND can solve systems of non-linear equations, linear and nonlinear optimisation problems, and dynamic systems expressed in the form of differential/algebraic equations. There is an '''[[ASCEND overview|ASCEND Overview]]''' with more information about ASCEND capabilities. Alternatively, you can look at some [[PyGTK Screenshots|screenshots]] or some [[Worked examples|example problems]] solved using ASCEND. <div style="padding-top:8px;padding-bottom:12px"><span style="border:solid 2pt gray;background-color:#ffff88;margin-top:5px;margin-bottom:5px;padding:8px">'''Current version 0.9.6''': [http://sourceforge.net/project/platformdownload.php?group_id=167528 Download] (Windows, Linux)</span></div> <font color=red>'''News flash:'''</font> Congratulations to [[Art Westerberg]] and his colleagues who have received the AIChE [http://www.cheme.cmu.edu/newsevents/news/archive/08-09/WarrenKLewis.htm Warren K. Lewis Award] for Chemical Engineering Education 2009. == In this wiki... == * some new [[:Category:Documentation|user's documentation]] (in progress) * some information on the various ASCEND [[solvers]]. * the [[Worked examples]] and the [[ModelLibrary]] for some examples of what you can do with ASCEND. * information on [[Building ASCEND]] from the source code * information about extending ASCEND using [[external libraries]]. * read about current [[Development activities]]. * the [[Developer's Manual]] in progress. * some ideas for [[Student Projects]] working on ASCEND. * please '''[[Debugging ASCEND|report a bug]]''' if you find one. This [http://en.wikipedia.org/wiki/Wiki wiki] is open to contributions from anyone. All we ask is that you [[Special:Userlogin|register]] with your email address. Note that there is some earlier content from our [http://ascend.cheme.cmu.edu/ascend_about.htm previous website] gradually being migrated to this wiki. == Get the source code == Source code (as well as binary) releases are available from our [http://sourceforge.net/project/platformdownload.php?group_id=167528 download page] on SourceForge. Open access to our [[VersionManagement|subversion repository]] is available, or you can [http://ascendcode.cheme.cmu.edu/ browse our code online]. == Send us your ASCEND models == We are working on expanding our [[ASCEND Model Library]]. If you have used ASCEND to solve a relatively common problem, your model will probably be of use to other users. Please contact [[Art Westerberg]] or one of the other developers if you are interested in sharing any models that you might have developed.
