Continuum Foam: A Material Point Method for Shear-Dependent Flows
Yue, Yonghao; Smith, Breannan; Batty, Christopher; Zheng, Changxi; Grinspun, Eitan (Association for Computing Machinery, 2015-10-01)We consider the simulation of dense foams composed of microscopic bubbles, such as shaving cream and whipped cream. We represent foam not as a collection of discrete bubbles, but instead as a continuum. We employ the ... -
Discrete viscous sheets
Batty, Christopher; Uribe, Andres; Audoly, Basile; Grinspun, Eitan (Association for Computing Machinery, 2012-07)We present the first reduced-dimensional technique to simulate the dynamics of thin sheets of viscous incompressible liquid in three dimensions. Beginning from a discrete Lagrangian model for elastic thin shells, we apply ... -
Double Bubbles Sans Toil and Trouble: Discrete Circulation-Preserving Vortex Sheets for Soap Films and Foams
Da, Fang; Batty, Christopher; Wojtan, Chris; Grinspun, Eitan (Association for Computing Machinery, 2015-08-01)Simulating the delightful dynamics of soap films, bubbles, and foams has traditionally required the use of a fully three-dimensional many-phase Navier-Stokes solver, even though their visual appearance is completely dominated ... -
A multi-scale model for coupling strands with shear-dependent liquid
Fei, Yun (Raymond); Batty, Christopher; Grinspun, Eitan; Zheng, Changxi (ACM, 2019-11)We propose a framework for simulating the complex dynamics of strands interacting with compressible, shear-dependent liquids, such as oil paint, mud, cream, melted chocolate, and pasta sauce. Our framework contains three ... -
A multi-scale model for simulating liquid-fabric interactions
Fei, Yun (Raymond); Batty, Christopher; Grinspun, Eitan; Zheng, Changxi (ACM, 2018-07)We propose a method for simulating the complex dynamics of partially and fully saturated woven and knit fabrics interacting with liquid, including the effects of buoyancy, nonlinear drag, pore (capillary) pressure, dripping, ... -
A Multi-scale Model for Simulating Liquid-hair Interactions
Fei, Yun (Raymond); Maia, Henrique Teles; Batty, Christopher; Zheng, Changxi; Grinspun, Eitan (Association for Computing Machinery, 2017-07-20)The diverse interactions between hair and liquid are complex and span multiple length scales, yet are central to the appearance of humans and animals in many situations. We therefore propose a novel multi-component simulation ... -
Multimaterial Mesh-Based Surface Tracking
Da, Fang; Batty, Christopher; Grinspun, Eitan (Association for Computing Machinery, 2014-07-01)We present a triangle mesh-based technique for tracking the evolution of three-dimensional multimaterial interfaces undergoing complex deformations. It is the first non-manifold triangle mesh tracking method to simultaneously ... -
Surface-Only Liquids
Da, Fang; Hahn, David; Batty, Christopher; Wojtan, Chris; Grinspun, Eitan (Association for Computing Machinery, 2016-07-01)We propose a novel surface-only technique for simulating incompressible, inviscid and uniform-density liquids with surface tension in three dimensions. The liquid surface is captured by a triangle mesh on which a Lagrangian ... -
A Unified Simplicial Model for Mixed-Dimensional and Non-Manifold Deformable Elastic Objects
Chang, Jumyung; Da, Fang; Grinspun, Eitan; Batty, Christopher (ACM, 2019-07)We present a unified method to simulate deformable elastic bodies consisting of mixed-dimensional components represented with potentially non-manifold simplicial meshes. Building on well-known simplicial rod, shell, and ...
