FluidsThe evolution of droplets during the printing process is modeled using the volume of fluid (VOF) method, which involves solving the NavierâStokes and continuity equations for incompressible flow with multiple immiscible phases on a finite volume grid. An indicator function tracks the interfaces and calculates surface tension forces. A grid independence
