Simulating Viscosity and Melting Fluids | Two Minute Papers #40

In this series, we have studied fluid simulations extensively. But we haven't talked about one important quantity that describes a fluid, and this quantity is none other than viscosity. Viscosity means the resistance of a fluid against deformation. The large viscosity of honey makes it highly resistant to deformation, and this is responsible for its famous and beautiful coiling effect. Water, however, does not have a lot of objections against deformations, making it so easy to pour it into a glass. With this piece of work, it is possible to efficiently simulate the motion of fluids, and it supports the simulation of a large range of viscosities.
