DWSIM API Reference

One page per simulation object and per property package. Each object page shows the object on a flowsheet, an example that runs on every build of this site, the calculation modes, the property IDs used from scripts and automation, and links to the user guide and to the tutorials that use it. Each property-package page gives the scope of the model, an example, the property methods and the settings saved with the flowsheet. The class members come last, in C# and VB.NET.
