Chaoyang Lyu, Wei Li, Mathieu Desbrun, Xiaopei Liu The intricate motions and complex vortical structures generated by the interaction between fluids and solids are visually fascinating. However, reproducing such a two-way coupling between thin objects and turbulent fluids numerically is … Continue reading →

Fast and Versatile Fluid-Solid Coupling for Turbulent Flow Simulation Predicting High-Resolution Turbulence Details in Space and Time Weatherscapes: Nowcasting Heat Transfer and Water Continuity Ships, Splashes, and Waves on a Vast Ocean A Material Point Method for Nonlinearly Magnetized Materials … Continue reading →

Nghia Truong, Cem Yuksel, Chakrit Watcharopas, Joshua A. Levine, Robert M. Kirby Robustly handling collisions between individual particles in a large particle-based simulation has been a challenging problem. We introduce particle merging-and-splitting, a simple scheme for robustly handling collisions between … Continue reading →

Xu Wang, Makoto Fujisawa, Masahiko Mikawa This paper introduces a method for simulating soil-structure coupling with water, which involves a series of visual effects, including wet granular materials, seepage flows, capillary action between grains, and dam breaking simulation. We develop … Continue reading →

Bruno Roy, Pierre Poulin, Eric Paquette We present a novel up-resing technique for generating high-resolution liquids based on scene flow estimation using deep neural networks. Our approach infers and synthesizes small- and large-scale details solely froma low-resolution particle-based liquid simulation. … Continue reading →

Seung Heon Sheen, Egor Larionov, Dinesh K. Pai Simulation of human soft tissues in contact with their environment is essential in many fields, including visual effects and apparel design. Biological tissues are nearly incompressible. However, standard methodsemploy compressible elasticity models … Continue reading →

Sheldon Andrews, Loic Nassif, Kenny Erleben, Paul Kry We present a novel meso-scale model for computing anisotropic and asymmetric friction for contacts in rigid body simulations that is based on surface facet orientations. The main idea behind our approach is … Continue reading →

Tassilo Kugelstadt, Jan Bender, José Antonio Fernández-Fernández, Stefan Rhys Jeske, Fabian Löschner and Andreas Longva We develop a new operator splitting formulation for the simulation of corotated linearly elastic solids with Smoothed Particle Hydrodynamics (SPH). Based on the technique of … Continue reading →

Tao Du, Kui Wu, Pingchuan Ma, Sebastien Wah, Andrew Spielberg, Daniela Rus, Wojciech Matusik We present a novel, fast differentiable simulator for soft-body learning and control applications. Existing differentiable soft-body simulators can be classified into two categories based on their … Continue reading →

Libo Huang, Ziyin Qu, Xun Tan, Xinxin Zhang, Dominik L. Michels, Chenfanfu Jiang The simulation of large open water surface is challenging for a uniform volumetric discretization of the Navier-Stokes equation. The water splashes near moving objects, which height field … Continue reading →
