Differentiate the Solver, Not the Equation: Reverse-Sweep Adjoints for Block Implicit Simulation
Lei Shu, Ying Jiang, Kui Wu +3
Differentiable simulation is a key component in learning, control, and inverse problems, where gradients through nonlinear implicit solvers are required. Existing approaches either…
WorldParticle: Unified World Simulation of Lagrangian Particle Dynamics via Transformer
Caoliwen Wang, Minghao Guo, Siyuan Chen +13
A unified simulator that can model diverse physical phenomena without solver-specific redesign is a long-standing goal across simulation science. We present a learning-based partic…
Handle-based Mesh Deformation Guided By Vision Language Model
Xingpeng Sun, Shiyang Jia, Zherong Pan +2
Mesh deformation is a fundamental tool in 3D content manipulation. Despite extensive prior research, existing approaches often suffer from low output quality, require significant m…
JGS2: Near Second-order Converging Jacobi/Gauss-Seidel for GPU Elastodynamics
Lei Lan, Zixuan Lu, Chun Yuan +5
In parallel simulation, convergence and parallelism are often seen as inherently conflicting objectives. Improved parallelism typically entails lighter local computation and weaker…
Volumetric Homogenization for Knitwear Simulation
Chun Yuan, Haoyang Shi, Lei Lan +6
This paper presents volumetric homogenization, a spatially varying homogenization scheme for knitwear simulation. We are motivated by the observation that macro-scale fabric dynami…
