Description

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.

Description

iGRAF is a comprehensive simulation tool that integrates powder and multiphase flow dynamics, effectively bridging the gap between these two domains. This innovative solution is tailored to accurately replicate a diverse array of powder behaviors while setting new benchmarks in simulation technology. With its advanced DEM-CFD solver, iGRAF provides users with the capability to perform precise analyses of both single-phase and multiphase flows, thereby enhancing the understanding of particle-fluid interactions within a unified platform. The tool's dynamic geometry control features allow for translations, rotations, vibrations, and customizable motion, enabling teams to effectively capture the intricate dynamics of complex systems. Additionally, it incorporates validated models for liquid bridging and van der Waals forces to evaluate the effects of moisture and adhesion on particle behavior, with its liquid bridge force model confirmed for moisture levels of up to 15%. Furthermore, iGRAF employs the Signed Distance Function along with the Immersed Boundary Method to adeptly identify and manage arbitrary solid geometries, ensuring flexibility in various applications. This versatility makes iGRAF an invaluable asset for researchers and engineers working with complex multiphase systems.
