Animating Coupling between Inviscid Free-Surface Liquids and Elastic Deformable Bodies
(University of Waterloo, 2017-08-16)Driven by demand for high-fidelity computer-generated imagery, physics-based animation has become an exciting frontier of research in computer science. Simulations of fluids and their interactions with other objects in the ... -
Discrete viscous sheets
(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 ... -
A fast variational framework for accurate solid-fluid coupling
(Association for Computing Machinery, 2007-07)Physical simulation has emerged as a compelling animation technique, yet current approaches to coupling simulations of fluids and solids with irregular boundary geometry are inefficient or cannot handle some relevant ... -
Matching fluid simulation elements to surface geometry and topology
(Association for Computing Machinery, 2010-07)We introduce an Eulerian liquid simulation framework based on the Voronoi diagram of a potentially unorganized collection of pressure samples. Constructing the simulation mesh in this way allows us to place samples anywhere ... -
Monolith: a monolithic pressure-viscosity-contact solver for strong two-way rigid-rigid rigid-fluid coupling
(Association for Computing Machinery, 2020-11)We propose Monolith, a monolithic pressure-viscosity-contact solver for more accurately, robustly, and efficiently simulating non-trivial two-way interactions of rigid bodies with inviscid, viscous, or non-Newtonian liquids. ... -
A Positive-definite Cut-cell Method for Strong Two-way Coupling Between Fluids and Deformable Bodies
(Association for Computing Machinery, 2017-07-28)We present a new approach to simulation of two-way coupling between inviscid free surface fluids and deformable bodies that exhibits several notable advantages over previous techniques. By fully incorporating the dynamics ... -
A practical octree liquid simulator with adaptive surface resolution
(Association for Computing Machinery, 2020-07)We propose a new adaptive liquid simulation framework that achieves highly detailed behavior with reduced implementation complexity. Prior work has shown that spatially adaptive grids are efficient for simulating large-scale ... -
Signorini conditions for inviscid fluids
(University of Waterloo, 2021-06-28)In this thesis, we present a new type of boundary condition for the simulation of inviscid fluids – the Signorini boundary condition. The new condition models the non-sticky contact of a fluid with other fluids or solids. ... -
Simulation of the Ferrofluid Interface
(University of Waterloo, 2020-05-14)Ferrofluids were initially invented as an additive for rocket fuels. The commercial applications of ferrofluids have since expanded, and have become popularized as desktop toys as well as an art form. Since 1987, ferrofluid ... -
Variational Stokes with Polynomial Reduced Fluid Model
(University of Waterloo, 2021-01-21)Standard fluid simulators often apply operator splitting to independently solve for pressure and viscous stresses. This decoupling, however, induces incorrect free surface boundary conditions. Such methods are unable to ...
