| 53 | <p>Le costnati degli Add sono state assegnate attraverso la costante One, invece che lasciarle come valore numerico in modo che esse non saranno visibili nella FMU una volta creata (con Dymola).</p>

| 54 | <p>Infatti correttamente Dymola non espone a maschera nella FMU le grandezze internamente assegnate con formule matematiche; sono invece esposti tutti i parametri asegnati in modo numerico.</p>
