What is it?

Chrono is an open-source C++ multi-physics package for modeling and simulating connected rigid bodies, deformable bodies governed by partial differential equations, granular media, and fluid-solid interaction. Optional modules extend it to ground vehicles, robots, co-simulation, run-time visualization, and parallel computing on multi-core, GPU, and distributed systems.

The core supports modeling, simulation, and visualization of rigid and flexible multibody systems. Sensor models for cameras, LiDAR, GPS, IMU, and SPAD are available for robotics and autonomous agent simulation through a ROS2 interface. Python (PyChrono) and C# APIs are provided alongside the C++ library, and the CMake-based build is tested on Linux, Windows, and macOS.
