CREA is aware that the challenge of concepts, together with the rapid development of new technologies in informatics and numerical analysis, rising new horizons for applied research and mathematical modelling, has just started. CREA, therefore, keeps working on its commitment to produce anyhow new concepts, to supply its customers with incomparable efficiency and reliability levels for any model it produces and sells.

Constantly proposing new concepts

To be ahead of times proposing constantly new ideas: rather than choice it is a matter of need for CREA, willing to be a leading company in the field of hydrodynamic mathematical modelling. Not only concepts, a number of which is used to develop graphical procedures to simplify users’ expensive job of preparing input files for mathematical models, but also in particular engineering and numerical knowledge, in order to create specific and exclusive algorithm and resolution methods to optimize and simulate hydrodynamic processes.


Interface graphs were created allowing to represent on a real scale each hydraulic element of the network and its plants in aqueduct and sewage systems, to simulate complex hydrodynamic systems such as bays and lagoons, to visualize autonomously territorial GIS, to prepare automatically databases and input files for the mathematical models.

Finite element mathematical models were developed which are able to simulate tidal wave propagation in Venice lagoon with absolutely extraordinary exactness.
Planning and management optimization procedures were established for aqueduct networks that are still incomparable.
Very innovative algorithms were proposed for the solution of transient motion equations in the systems of shallow flow, using the technique of finite elements and the method of characteristics in order to avoid problems of numerical diffusion and to describe in detail complex geometries.
