An adaptive variational finite difference framework for efficient symmetric octree viscosity
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
We present an efficient geometric Multigrid solver for simulating viscous liquids based on the variational approach of Batty and Bridson . Although the governing equations for viscosity are elliptic, the strong ...
A Unified Simplicial Model for Mixed-Dimensional and Non-Manifold Deformable Elastic Objects
We present a unified method to simulate deformable elastic bodies consisting of mixed-dimensional components represented with potentially non-manifold simplicial meshes. Building on well-known simplicial rod, shell, and ...
A multi-scale model for coupling strands with shear-dependent liquid
We propose a framework for simulating the complex dynamics of strands interacting with compressible, shear-dependent liquids, such as oil paint, mud, cream, melted chocolate, and pasta sauce. Our framework contains three ...
Mandoline: robust cut-cell generation for arbitrary triangle meshes
Although geometry arising "in the wild" most often comes in the form of a surface representation, a plethora of geometrical and physical applications require the construction of volumetric embeddings either of the geometry ...
