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 ... -
Power Diagrams and Sparse Paged Grids for High Resolution Adaptive Liquids
Aanjaneya, Mridul; Gao, Ming; Liu, Haixiang; Batty, Christopher; Sifakis, Eftychios (Association for Computing Machinery, 2017-07-20)We present an efficient and scalable octree-inspired fluid simulation framework with the flexibility to leverage adaptivity in any part of the computational domain, even when resolution transitions reach the free surface. ...
