Adaptive GPU Kinetic Solver for Fluid-Granular Flows
Xingqiao Li, Kui Wu, Haozhe Su +5
Simulating fluid-granular flows is crucial for understanding natural disasters, industrial processes, and visually realistic phenomena in computer graphics. These systems are chall…
Substepping the Material Point Method
Chenfanfu Jiang
Many Material Point Method implementations favor explicit time integration. However large time steps are often desirable for special reasons - for example, for partitioned coupling…
Neural Stress Fields for Reduced-order Elastoplasticity and Fracture
Zeshun Zong, Xuan Li, Minchen Li +6
We propose a hybrid neural network and physics framework for reduced-order modeling of elastoplasticity and fracture. State-of-the-art scientific computing models like the Material…
A Contact Proxy Splitting Method for Lagrangian Solid-Fluid Coupling
Tianyi Xie, Minchen Li, Yin Yang +1
We present a robust and efficient method for simulating Lagrangian solid-fluid coupling based on a new operator splitting strategy. We use variational formulations to approximate f…
Affine Body Dynamics: Fast, Stable & Intersection-free Simulation of Stiff Materials
Lei Lan, Danny M. Kaufman, Minchen Li +2
Simulating stiff materials in applications where deformations are either not significant or can safely be ignored is a pivotal task across fields. Rigid body modeling has thus long…
Ships, Splashes, and Waves on a Vast Ocean
Libo Huang, Ziyin Qu, Xun Tan +3
The simulation of large open water surface is challenging using a uniform volumetric discretization of the Navier-Stokes equations. Simulating water splashes near moving objects, w…
Codimensional Incremental Potential Contact
Minchen Li, Danny M. Kaufman, Chenfanfu Jiang
We extend the incremental potential contact (IPC) model for contacting elastodynamics to resolve systems composed of codimensional DOFs in arbitrary combination. This enables a uni…
A Hybrid Lagrangian/Eulerian Collocated Advection and Projection Method for Fluid Simulation
Steven W. Gagniere, David A. B. Hyde, Alan Marquez-Razon +5
We present a hybrid particle/grid approach for simulating incompressible fluids on collocated velocity grids. We interchangeably use particle and grid representations of transporte…
Hierarchical Optimization Time Integration for CFL-rate MPM Stepping
Xinlei Wang, Minchen Li, Yu Fang +5
We propose Hierarchical Optimization Time Integration (HOT) for efficient implicit time-stepping of the Material Point Method (MPM) irrespective of simulated materials and conditio…
Fast and Scalable Position-Based Layout Synthesis
Tomer Weiss, Alan Litteneker, Noah Duncan +4
The arrangement of objects into a layout can be challenging for non-experts, as is affirmed by the existence of interior design professionals. Recent research into the automation o…
Position-Based Multi-Agent Dynamics for Real-Time Crowd Simulation (MiG paper)
Tomer Weiss, Alan Litteneker, Chenfanfu Jiang +1
Exploiting the efficiency and stability of Position-Based Dynamics (PBD), we introduce a novel crowd simulation method that runs at interactive rates for hundreds of thousands of a…
