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. __________________________ The paper "An Implicit Viscosity Formulation for SPH Fluids" is available here: http://cg.informatik.uni-freiburg.de/publications/2015_SIGGRAPH_viscousSPH.pdf Recommended for you: Painting with Fluid Simulations - https://www.youtube.com/watch?v=1aVSb-UbYWc Modeling Colliding and Merging Fluids - https://www.youtube.com/watch?v=uj8b5mu0P7Y Adaptive Fluid Simulations - https://www.youtube.com/watch?v=dH1s49-lrBk Video source: Smarter Every Day - https://www.youtube.com/watch?v=zz5lGkDdk78 The thumbnail image was created by Dino Giordano (CC BY 2.0) - https://flic.kr/p/4p9z4w Subscribe if you would like to see more of these! - http://www.youtube.com/subscription_center?add_user=keeroyz Splash screen/thumbnail design: Felícia Fehér - http://felicia.hu Károly Zsolnai-Fehér's links: Patreon → https://www.patreon.com/TwoMinutePapers Facebook → https://www.facebook.com/TwoMinutePapers/ Twitter → https://twitter.com/karoly_zsolnai Web → https://cg.tuwien.ac.at/~zsolnai/
