Simulators
The word “simulator” generally refers to a mathematical (virtual) model of reality, setted to react in a plausible way to specific physical conditions. For example, a flight simulator reproduce, in a virtual environment, the flight experience, reproducing the engine noise, the controllers reaction, the air resistance, the pressure and so on.
There are many possible applications for simulators, especially in the mechanical field: they can be used to train qualified personnel working with a specific machine or to test industrial prototypes to a relatively low cost or, again, to develop video games and immersive virtual reality games.
