Independently from the simplicity of the use of the informatic tool, able to disguise the complexities of the numerical algorithms of the mathematical models through a powerful and effective graphic interface, the simulation of the real physical systems complexity necessarily imposes a deep and specific experience. They are not often appraised sufficiency the problems tied up the correct application of the models, which, not rarely, hide numerical problems recognizable only to the experts of the sector. In this sense, it must be kept in mind that only a minimum part of the adopted numerical algorithms is able to faithfully represent, with pretension of generality, the complex physical real processes that the same models try to simulate. As many often, technical without scruples force the numerical simulators to correspond in all the ways, permissible or less, to the reality, with serious consequences on the base of the results and the deducible forecasts subsequently from the same informatic tools.

At this purpose the notable applications of the mathematical models performed by the CREA technicians qualify the competence of the company in this sector of activity.

Just reached the objective to realize the correct correspondence between the real physical system and the mathematical model, the personnel of the corporate will be put however in condition to autonomously manage the realized informative tool. From this point in then, eventually also with the aid and the support of the CREA personnel, the company's personnel will provide to adjourn autonomously the informations contained in the databases, the characteristics of the plants, the extensions of the networks, the variations in the structure of the physical systems of interest…
