During numerical simulation, one of the biggest challenges is to simulate the smallest air bubbles that can be entrained in the metal. In fact, in common fluid dynamic simulation of casting process filling each time a region of air gets smaller than the element size it disappears, losing all the information about its presence and the possible defects that this implies. If the engineers with enough experience and good background, who can track the regions of air entrapped during the filling process and check manually where they, especially the last ones, close up and disappear. However, this approach is too approximated and does not keep in account the final movement displacement of the bubble.
