Why would SMS Demag start Why would SMS Demag start developing SimuSage?developing SimuSage?

• Integrated Thermodynamic Databank Systems such as FactSage are great tools for point calculations, range calculations, phase diagrams, etc.

• What about processes, i.e. multiple reactors interconnected via streams? Recycle/feedback streams? Dynamic behaviour? A library of other unit operations like mixers, splitters, heat exchangers?

• What about doing this quickly, with a minimum amount of coding? Including a user interface that somebody other than the developer can use?

• And what if you want to give your ready-made simulation to somebody else?
