About

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.

About

iGRAF is an integrated powder and multiphase flow simulation tool that seamlessly merges the domains of powder and fluid simulation. It is designed as a one-stop solution for replicating a wide variety of powder behaviors and redefining standards in simulation technology. iGRAF’s integrated DEM-CFD solver enables accurate and efficient analysis of single-phase and multiphase flow, helping users understand particle-fluid interactions in one platform. Its dynamic geometry control supports translations, rotations, vibrations, and user-defined motion, allowing teams to precisely capture the dynamics of complex systems. It includes validated liquid bridging models and van der Waals forces to analyze the influence of moisture and adhesion on particle behavior, with its liquid bridge force model extensively validated up to 15% moisture content. iGRAF also combines the Signed Distance Function and Immersed Boundary Method to recognize arbitrary solid geometries.
