Project Chrono is a high-performance, open-source C++ multiphysics simulation library for multibody dynamics, finite element analysis, granular dynamics, fluid-solid interaction, and vehicle/robot simulation. It offers optional modules for sensors, GPU parallel computing, co-simulation, and provides Python (PyChrono) and C# APIs.
Use cases
- simulate wheeled and tracked vehicles on deformable terrain
- simulate robots and autonomous agents with camera, LiDAR, GPS, and IMU sensors
- model granular material flows with millions of bodies on GPU
- perform nonlinear finite element analysis of compliant mechanisms
- simulate fluid-solid interaction problems
- model multibody mechanisms with joints, motors, springs, and contacts
- export SolidWorks CAD assemblies into a physics simulation
- run embodied AI and terramechanics research simulations
When to choose
- you need physics-accurate multibody or FEA simulation rather than game-style physics
- you simulate vehicles, robots, or granular media at engineering fidelity
- you need GPU or multicore parallelism for large-scale simulations
- you want a permissive BSD-3 licensed embeddable C++ engine with Python bindings
When to avoid
- you need a GUI-driven simulation tool out of the box
- you only need fast game-style physics for a video game (Bullet, PhysX may suffice)
- you need a lightweight, easy-to-learn scripting-only simulator
- your project cannot handle building a large C++ codebase with CMake
