Struttura Informatica provides engineering consulting services for industrial plants and for power plants. Using dynamic simulation and CFD, Struttura Informatica carries out for its customers mainly consulting activities and support to the Basic Design. ISAAC Dynamics by Struttura Informatica is a complete tool for modeling and simulation of integrated and complex systems. The tool permits to build dynamic models that are accurate and efficacious, thanks to its innovative technical features: - architecture by modules, designed to represent a specific plant system as a group of logically connected block modules selected from the ready made module libraries; - availability of a powerful and user friendly graphic interface designed to make the development particularly efficient and accurate; - it produces autonomous application programs that do not require licensing of the development system to be run in the form of application; it is supplied with standard libraries of modules specifically applied for the technological sectors in question, with the possibility of further implementations for specific requisites; - it includes thermodynamic tables of the main fluids to be used as system blocks or accessed through user interface in order to calculate the thermodynamic quantities of interest.
