DWSIM is an open-source CAPE-OPEN
compliant chemical process simulator for Windows and Linux. Built on
the top of the Microsoft .NET 4.0 and Mono Platforms and featuring a
rich Graphical User Interface (GUI), DWSIM allows chemical engineering
students and chemical engineers to better understand the behavior of
their chemical systems by using rigorous thermodynamic and unit
operations' models with no cost at all. Since DWSIM is open source, they
can see how the calculations are actually being done by inspecting the
code behind during execution using free tools available elsewhere.
DWSIM has an easy-to-use graphical interface with many features previously available only in commercial simulators:
