This open-source software facilitates the transfer of material stream information between compliant flowsheet simulation environments using CAPE-OPEN technology. Information is stored in XML, making it compatible with other XML-capable applications.

The FlowExchange package comprises of two unit operations: XFlowSaver and XFlowLoader. The XFlowSaver unit operation is designed to save an XFlow file in a product stream or intermediate stream within a flowsheet, while the XFlowLoader unit operation is used to define a feed stream in a flowsheet to read an existing XFlow file and define the product stream.
The XFlow file format is an open XML file format specifically designed to exchange material stream data between flowsheet simulators. Files are written and read by the XFlowSaver and XFlowLoader unit operations respectively, but third-party applications are easily able to parse or write XFlow files. Users can configure the level of detail saved in an XFlow file by the XFlowSaver. Additionally, the XFlow file format specification and an example of .XFlow file content are provided for user convenience.
For users interested in viewing and comparing XFlow files, the FlowExchange package includes a standalone tool specifically designed for this purpose.
The FlowExchange package is built using Visual Studio 2015, utilizing the .NET 4.5.1 platform. The source code is available to users and is included in the package installer. As it is an open-source tool, the FlowExchange package is available free-of-charge for users who wish to take advantage of its many benefits.
