Abstract
A system and method for simulating the flow of a viscoelastic fluid through a channel. The simulation including a interface between a first fluid and a second fluid. The simulation including the formation of a droplet. The simulation includes solving equations governing the viscoelastic flow of the first fluid through the channel, including viscoelastic stress equations that include a normalized relaxation time greater than or equal to 5. The calculations simulate the flow of the first fluid through the channel. The simulation is stable over a period time in which a droplet is formed. The simulation including a level set function that describes the position of the interface between the first and second fluids, and the evolution of the level set function over time describes the shape and position of the interface.
