Fire Dynamics Simulator (FDS) serves as a free and open-source platform for the modeling and visualization of flows influenced by fire. This computational fluid dynamics code effectively solves a variant of the Navier–Stokes equations tailored for low-speed, thermally-driven airflow, focusing particularly on the transport of smoke and heat resulting from fires. Employing large-eddy simulation, it captures the intricacies of fire-plume dynamics and can be utilized in diverse scenarios, such as those involving wind, sprinklers, ventilation systems, and various materials that affect fire behavior. Users create scenarios by utilizing text-based input files, execute the calculations within FDS, and subsequently evaluate the output data. The simulator presents results from both FDS and CFAST simulations through advanced OpenGL-based 3D graphics, incorporating scientific visualization techniques that include animated representations of smoke and tracer particles, two- and three-dimensional shaded contours, iso-surfaces, temperature distributions, and flow vectors that display both direction and intensity. In addition to these features, FDS is continually updated to enhance user experience and functionality, making it a vital tool for researchers and safety professionals alike.

PyBullet is a versatile Python library designed for simulating physics, robotics, and deep reinforcement learning, and it is rooted in the Bullet Physics SDK. This module enables users to load articulated bodies from various formats such as URDF and SDF, while also offering capabilities like forward dynamics simulation, inverse dynamics computation, kinematics, collision detection, and ray intersection queries. In addition to its robust simulation features, PyBullet includes rendering options, such as a CPU renderer and OpenGL visualization, along with support for virtual reality headsets. It finds applications in numerous research initiatives, including Assistive Gym, which utilizes PyBullet to facilitate physical human-robot interactions and advance assistive robotics for collaborative and physically supportive tasks. Additionally, the Kubric project serves as an open-source Python framework that collaborates with PyBullet and Blender to create photorealistic scenes complete with detailed annotations, demonstrating its ability to scale to extensive projects that can be distributed across thousands of machines. This combination of functionalities makes PyBullet an essential tool for researchers and developers working in the fields of robotics and simulation.
