Journal ArticleDOI
Continuum Foam: A Material Point Method for Shear-Dependent Flows
TL;DR: This work employs the material point method to discretize a hyperelastic constitutive relation augmented with the Herschel-Bulkley model of non-Newtonian viscoplastic flow, which is known to closely approximate foam behavior.
Journal ArticleDOI
Discrete viscous sheets
TL;DR: This work applies the Stokes-Rayleigh analogy to derive a simple yet consistent model for viscous forces that incorporates nonlinear surface tension forces with a formulation based on minimizing discrete surface area, and preserves the quality of triangular mesh elements through local remeshing operations.
Journal ArticleDOI
Multimaterial mesh-based surface tracking
TL;DR: This work presents a triangle mesh-based technique for tracking the evolution of three-dimensional multimaterial interfaces undergoing complex deformations, and is the first non-manifold triangle mesh tracking method to simultaneously maintain intersection-free meshes and support the proposed broad set of multimaterial remeshing and topological operations.
Journal ArticleDOI
Surface-only liquids
TL;DR: A novel surface-only technique for simulating incompressible, inviscid and uniform-density liquids with surface tension in three dimensions, using an orthogonal projection technique to remove the divergence while requiring the evaluation of only two boundary integrals.
Journal ArticleDOI
Double bubbles sans toil and trouble: discrete circulation-preserving vortex sheets for soap films and foams
TL;DR: A novel circulation-preserving surface-only discretization of foam dynamics driven by surface tension on a non-manifold triangle mesh that is at once simple, robust, and efficient, yet able to capture an array of soap films behaviors including foam rearrangement, catenoid collapse, blowing bubbles, and double bubbles being pulled apart.
