Support the Project

Previous donations have already been very helpful on supporting development of new features and bringing DWSIM to new platforms (Raspberry Pi, macOS, Android, iOS). As DWSIM becomes more mature, development efforts must go towards more complex, specific models and systems. As complexity increases, more effort (= time and money) is required.

By becoming a patron, you will support future development of DWSIM while getting access to exclusive support channels and features, including custom-made plug-ins/add-ins which won't be distributed to anyone else except you.

Platform-specific Details

DWSIM for Windows

DWSIM is available for 32 and 64-bit Windows 7, 8 and 10 systems. Administrator privileges are not required for the installation of DWSIM itself, but do are for .NET Type Libraries Registration (to enable Automation) and installation of the supplementary software. Requires Microsoft .NET Framework 4.7.1.

DWSIM Classic UI on Windows

When running DWSIM on Windows you have the choice of two Graphical User Interfaces (GUIs): Classic and Cross-Platform, the latter also being known as 'New' UI. The Classic UI is the Windows Forms-based, fully-featured one.

DWSIM Cross-Platform UI on Windows

The Cross-Platform UI is WPF-based and may look better on High-DPI displays, although it doesn't have the same feature set as the Classic UI one.

CAPE-OPEN is much better supported on the Classic UI than on the Cross-Platform one and, because of that, it is the recommended interface when working with CAPE-OPEN software like ChemSep and COCO components.

Support for Free Download Users is available on the SourceForge Forums only. Direct emails asking for help/support will be ignored.

DWSIM Patrons support future development, have early access to updates and direct email support.

DWSIM for Linux

DWSIM is available for 64-bit (amd64) Debian-based Linux systems. DWSIM on Linux requires Mono Framework version 5.14 or newer to run. The Debian Installer Package takes care of the required dependencies.

DWSIM Classic UI on Linux

When running DWSIM on Linux you have the choice of two Graphical User Interfaces (GUIs): Classic and Cross-Platform, the latter also being known as 'New' UI. The Classic UI is the Windows Forms-based one, which when running on Linux may exhibit some bugs because it is not Linux-native.

DWSIM Cross-Platform UI on Linux

On the other hand, the Cross-Platform UI is based on the Eto library which, when running on Linux, displays a GTK2-based interface, which looks native and is much faster the the Classic one:

The Classic UI can be launched by typing dwsim-classic on the terminal, and the Cross-Platform one can be launched by typing dwsim.
