An adaptive variational finite difference framework for efficient symmetric octree viscosity
(ACM, 2019-07)While pressure forces are often the bottleneck in (near-)inviscid fluid simulations, viscosity can impose orders of magnitude greater computational costs at lower Reynolds numbers. We propose an implicit octree finite ... -
An Efficient Geometric Multigrid Solver for Viscous Liquids
(ACM, 2019-07)We present an efficient geometric Multigrid solver for simulating viscous liquids based on the variational approach of Batty and Bridson [2008]. Although the governing equations for viscosity are elliptic, the strong ... -
The modeling of blood rheology in small vessels
(University of Waterloo, 2005)Blood is a dense suspension of flexible red blood cells. In response to a background flow, these cells distribute themselves non-uniformly throughout the vessel. As a result, material properties that are well defined ... -
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. ... -
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 ... -
Variational Stokes: A Unified Pressure-viscosity Solver for Accurate Viscous Liquids
(Association for Computing Machinery, 2017-07-20)We propose a novel unsteady Stokes solver for coupled viscous and pressure forces in grid-based liquid animation which yields greater accuracy and visual realism than previously achieved. Modern fluid simulators treat ...
