Bastian Abt, David Stotko, Nils Wandel, Reinhard Klein Simulating inviscid, incompressible fluids on non-simply-connected curved surfaces requires careful treatment of the flow’s local and global behavior. While recent theoretical advancements have established the critical dynamics of the harmonic component in … Continue reading →

Yixin Chen, David I.W. Levin, Timothy R. Langlois We present a physics-based fluid control method utilizing localized spacetime windows, extending force-based fluid control to substantially larger simulation scales. In many practical editing scenarios, user-specified objectives affect only a small region … Continue reading →

Hongcheng Song, Ye Fan, Uri M. Ascher, Dinesh K. Pai Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form. However, in its … Continue reading →

Bernhard Braun, Rene Winchenbach, Jan Bender, Nils Thuerey We present ST-FLIP, a spatiotemporal extension of the Fluid-Implicit Particle (FLIP) method for incompressible free-surface and two-phase liquid simulation. ST-FLIP enables time steps up to an order of magnitude larger than those … Continue reading →

Shixun Huang, Siyuan Chen, Yue Chang, Zhecheng Wang, Peter Yichen Chen Cyclic animation is widely used in computer graphics and interactive content. It supports seamless playback in games, VR, and interactive simulation, where short clips must repeat smoothly over long … Continue reading →

Rupesh Kumar, Sabhya Khurana, Rahul Narain We present a technique for simulating detailed cloth dynamics on coarse meshes at interactive rates, by coupling the base mesh simulation with dynamic wrinkles in a physically consistent manner. Building on the wrinkle parameterization … Continue reading →

Kangrui Zhang, Ruihong Cen, Siyan Zhu, Ruoyan Chen, Bo Ren We present DIQ-MPM, a novel monolithic two-way coupling framework for simulating interactions between solids modeled with the total Lagrangian formulation and Eulerian incompressible fluids using the Material Point Method (MPM). … Continue reading →

Gilles Daviet We present a family of mixed Material Point Methods well suited to CFL-rate simulation of stiff elastoviscoplastic materials, up to the incompressible limit. Our work builds on the mixed discretization from Daviet and Bertails-Descoubes [2016a] and extends it … Continue reading →

Li Liao, Pengfei Shen, Yifan Peng Eigenanalysis of partial differential operators is central to reduced-order physical simulation, but neural shape-space eigenanalysis has largely been limited to natural Neumann boundary conditions. This prevents direct control over supports, openings, heat-exchange boundaries, and … Continue reading →
