The FlowExchange package consists out of two unit operations:

The XFlow file format is an open, XML based, file format designed to exchange material stream data between flowsheet simulators. XFlow files are written by the XFlowSaver unit operation and read by the XFlowLoader unit operation, but any 3rd party application can easily parse or write XFlow files. The level of detail that are saved in an XFlow file by the XFlowSaver is configurable. The .XFlow file format specification is available here; also see this example .XFlow file content.

The FlowExchange package includes a stand-alone viewer and comparison tool for XFlow files.
