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…
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…
MBD-NODE: Physics-informed data-driven modeling and simulation of constrained multibody systems
Jingquan Wang, Shu Wang, Huzaifa Mustafa Unjhawala +2
We describe a framework that can integrate prior physical information, e.g., the presence of kinematic constraints, to support data-driven simulation in multi-body dynamics. Unlike…
Chrono DEM-Engine: A Discrete Element Method dual-GPU simulator with customizable contact forces and element shape
Ruochun Zhang, Bonaventura Tagliafierro, Colin Vanden Heuvel +6
This paper introduces DEM-Engine, a new submodule of Project Chrono, that is designed to carry out Discrete Element Method (DEM) simulations. Based on spherical primitive shapes, D…
A GPU-accelerated simulator for the DEM analysis of granular systems composed of clump-shaped elements
Ruochun Zhang, Colin Vanden Heuvel, Alexander Schepelmann +5
We discuss the use of the Discrete Element Method (DEM) to simulate the dynamics of granular systems made up of elements with nontrivial geometries. The DEM simulator is GPU accele…
Constrained multibody kinematics and dynamics in absolute coordinates: a discussion of three approaches to representing rigid body rotation
A. Kissel, J. Taves, D. Negrut
We compare three approaches to posing the index 3 set of differential algebraic equations (DAEs) associated with the constrained multibody dynamics problem formulated in absolute c…
Producing 3D Friction Loads by Tracking the Motion of the Contact Point on Bodies in Mutual Contact
Luning Fang, Dan Negrut
We outline a phenomenological model to assess friction at the interface between two bodies in mutual contact. Although the approach is general, the application inspiring the approa…
