An adaptive variational finite difference framework for efficient symmetric octree viscosity
Goldade, Ryan; Wang, Yipeng; Aanjaneya, Mridul; Batty, Christopher (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 ... -
Constraint bubbles and affine regions: reduced fluid models for efficient immersed bubbles and flexible spatial coarsening
Goldade, Ryan; Aanjaneya, Mridul; Batty, Christopher (Association for Computing Machinery, 2020-07)We propose to enhance the capability of standard free-surface flow simulators with efficient support for immersed bubbles through two new models: constraint-based bubbles and affine fluid regions. Unlike its predecessors, ... -
An Efficient Geometric Multigrid Solver for Viscous Liquids
Aanjaneya, Mridul; Han, Chengguizi; Goldade, Ryan; Batty, Christopher (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 ... -
A Practical Method for High-Resolution Embedded Liquid Surfaces
Goldade, Ryan; Batty, Christopher; Wojtan, Chris (Wiley, 2016-05-01)Combining high-resolution level set surface tracking with lower resolution physics is an inexpensive method for achieving highly detailed liquid animations. Unfortunately, the inherent resolution mismatch introduces several ...
