ChronoAgentic: A Code-based Multi-Agent World Simulator for Physically Grounded Simulation Construction
Hongyu Wang, Jingquan Wang, Bocheng Zou +3
Video-based world models generate visually plausible rollouts, but since they infer dynamics in latent states, they enforce no explicit physical constraints: contacts drift, shapes…
Chrono-Gymnasium: An Open-Source, Gymnasium-Compatible Distributed Simulation Framework
Bocheng Zou, Harry Zhang, Khailanii Slaton +5
High-fidelity physics simulation is essential for closing the sim-to-real gap in robotics and complex mechanical systems. However, the computational overhead of high-fidelity engin…
Chrono::Ray: A Distributed Framework for High-Throughput Simulation-Based Analysis of Multibody Systems
Khailanii Slaton, Dan Negrut
Large-scale simulation studies can provide invaluable insights across computational engineering efforts, but they are often computationally demanding, requiring the use of distribu…
Active Learning for Communication Structure Optimization in LLM-Based Multi-Agent Systems
Huchen Yang, Xinghao Dong, Dan Negrut +1
Optimizing the communication structure of large language model based multi-agent systems (LLM-MAS) has been shown to improve downstream performance and reduce token usage. Existing…
A Total Lagrangian Finite Element Framework for Multibody Dynamics: Part II -- GPU Implementation and Numerical Experiments
Zhenhao Zhou, Ruochun Zhang, Ganesh Arivoli +1
We present the numerical methods and GPU-accelerated implementation underlying a Total Lagrangian finite element framework for finite-deformation flexible multibody dynamics, intro…
FNODE: Flow-Matching for data-driven simulation of constrained multibody systems
Hongyu Wang, Jingquan Wang, Dan Negrut
Data-driven modeling of constrained multibody dynamics remains challenged by (i) the training cost of Neural ODEs, which typically require backpropagation through an ODE solver, an…
