DWSIM is an open-source CAPE-OPEN compliant chemical process simulator for Windows, Linux and macOS. DWSIM is built on top of the Microsoft .NET and Mono Platforms and features a Graphical User Interface (GUI), advanced thermodynamics calculations, reactions support and petroleum characterization / hypothetical component generation tools.

DWSIM is able to simulate steady-state, vapor–liquid, vapor–liquid-liquid, solid–liquid and aqueous electrolyte equilibrium processes with the following Thermodynamic Models and Unit Operations:

Android and iOS versions

DWSIM is also available on Android and iOS mobile operating systems, where it is free to download. On these platforms, DWSIM includes a basic set of features while more advanced modules can be unlocked through in-app purchases.[4]

Raspberry Pi version

A special DWSIM build is available for Raspberry Pi 2/3 devices running an armhf-based Linux distribution like Raspbian and Ubuntu MATE.[5]
