What is Pyrosim?

Pyrosim is a graphical user interface for the Fire Dynamics Simulator (FDS), a computational fluid dynamics (CFD) software developed by NIST (National Institute of Standards and Technology) for simulating fire-driven fluid flow. Pyrosim simplifies the creation and management of FDS simulations, providing tools for geometry creation, material property assignment, mesh generation, and visualization of results. It is commonly used for fire protection engineering, including smoke control design, evacuation analysis, and fire reconstruction.
