Text2Sim: Agentic Physics-Based Simulation Generation with Distilled Expertise
Xiaoyu Xiong, Tsun-Hsuan Wang, Yi-Ling Qiao +2
Creating diverse physical simulations remains labor-intensive because assets, layout, physical parameters, motion, control, and rendering must be designed and debugged jointly. We…

AGIPC: Adaptive In-Solve Algebraic Coarsening for GPU IPC
Xuan Wang, Zhaofeng Luo, Minchen Li +2
Implicit time integration is key to robustly simulating stiff materials and large deformations, but its performance is often dominated by repeatedly solving large linear systems. A…
