DIVA - AN OPEN ARCHITECTURE FOR DYNAMIC SIMULATION

During 3 yr of application of the dynamic flowsheet simulator DIVA, existing features have been extended and new capabilities have been added. This expansion leads to an improved open architecture for the dynamic simulation environment. Interfaces are developed for interactive communication with the user during all stages of the simulation. A graphical flowsheet editor is used to define the simulation problem. The execution of a simulation problem is organized in separately operable tasks including the simulator, system theoretical methods, a graphic utility and a post processor. For real-time application a data management system and a real-time process interface are implemented. Communication among all tasks is divided into a command transfer level and a process database.
