Fire Dynamics Simulator (FDS)
Fire Dynamics Simulator (FDS) is a free, open source tools for modeling and visualizing fire-driven flows. FDS is a computational fluid dynamics code that numerically solves a form of the Navier–Stokes equations for low-speed, thermally driven flow, with particular emphasis on smoke and heat transport from fires. It uses large-eddy simulation to represent complex fire-plume dynamics and can be applied to scenarios involving fire, wind, sprinklers, ventilation, geometry, materials, and other conditions that influence fire behavior. Users define a scenario through text-based input files, run the calculation with FDS, and analyze the resulting data. It displays output from FDS and CFAST simulations using OpenGL-based 3D graphics and scientific visualization methods, including animated smoke and tracer particles, two- and three-dimensional shaded contours, iso-surfaces, temperature fields, and flow vectors showing direction and magnitude.

FireFlow Studio for FDS
FireFlow Studio for FDS is a fully integrated Windows GUI for NIST's Fire Dynamics Simulator (FDS), built by a practising fire safety engineer for fire engineering consultancies. It covers the complete workflow in one application: 3-D geometry modelling with DXF floor-plan tracing and automatic voxelisation of arcs and circles, multi-mesh setup with visible cells and MPI splitting, a guided fire-design wizard with a D* flame-resolution calculator, one-click runs of the bundled unmodified FDS solver with live monitoring of HRR and device outputs, and an integrated 3-D results viewer with slices, boundary quantities, smoke rendering, scenario-comparison tabs and CSV/PNG export. A built-in finite-element heat-transfer solver is live-coupled to the running FDS simulation, so structural steel temperatures develop alongside the fire with no external FEA package. Hand-written FDS decks round-trip.

Particleworks
Particleworks is particle-based CAE and CFD software for simulating liquid and multiphase flows using the Moving Particle Simulation method. Its mesh-less solver and intuitive interface make the simulation process simple and fast, even for complex geometries with moving parts such as transmissions, electric motors, internal combustion engines, and other industrial systems. Unlike conventional mesh-based CFD, Particleworks discretizes the fluid domain automatically with particles, eliminating complex mesh generation and making it easier to analyze free-surface flow, splashing, sloshing, spraying, mixing, lubrication, cooling, oil behavior, water interaction, and highly viscous fluids. It provides one-stop GUI operation from pre-processing through post-processing, helping engineers set up models, run simulations, visualize results, and evaluate performance in a streamlined workflow.
