About DWSIM

DWSIM is a Chemical Process Simulator for Windows. Built on the Microsoft .NET 2.0 Platform 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. Even better, they can see how the calculations are actually being done - DWSIM is open source, that is, its code is available to anyone who wishes to discover the "magic" behind it or just do some browsing.

If you are familiar with Aspen HYSYS (from Aspentech) or UNISIM Design (from Honeywell), you won't have any problems using DWSIM.
