Hello everyone,

My name is Daniel and i'm the developer of DWSIM, an open-source chemical process simulator developed in VB.NET. DWSIM is released under the GPL v3 license, and it is hosted
at the SourceForge website (http://sourceforge.net/projects/dwsim/). This version is fully translated to English, including documentation (though the online help file is not as nearly complete as the Brazilian Portuguese version, but the PDF manuals are the same).

DWSIM includes the most common unit operations (including reactors) and thermodynamic packages found in commercial simulators. Still missing are distillation towers and heat exchangers (these probably will appear in the next version).

You can also find in the Downloads page an example simulation (Cavett's problem) in order to view some of DWSIM's main features.The source code can be compiled with Visual Basic 2005 Express Edition (a free Visual Studio VB.NET specific version).

Please post your comments, sugestions and questions etc. in the Forums section. They will be answered as soon as possible.

There is also a growing effort to make DWSIM run in Mono. Any help is very appreciated.

Thank you!
Daniel
