1.1.1 Event DrivenThis concept combines the power of interactive simulation with instantaneous access to information. Interactive simulation means the information is processed as it is supplied and calculations are performed automatically. Also, you are not restricted to the program location where the information is supplied.

1.1.2 Modular OperationsModular Operations are combined with the Non-Sequential solution algorithm. Not only is information processed as it is supplied, but the results of any calculation are automatically produced throughout the flowsheet, both forwards and backwards. The modular structure of the operations means they can be calculated in either direction, using information in an outlet stream to calculate inlet conditions. Process understanding is gained at every step because the operations calculate automatically and results are seen immediately.

1.1.3 Multi-flowsheet ArchitectureMulti-flowsheet architecture can be used to create any number of flowsheets within a simulation and to easily associate a fluid package with a defined group of unit operations.
