NIST’s XX Building and Fire Research Laboratory develops and maintains a computational fluid dynamics software package for modeling building and wildland fires called the Fire Dynamics Simulator (FDS). FDS is a block structured Cartesian LES code for low-speed flow, tuned specifically for fire dynamics. The goal of this project is to free FDS from the prison of static, uniform grids. Fire spread in buildings and wildlands is a problem begging for adaptive mesh methods. The domains of interest are typically several orders of magnitude larger than the dynamical length scales of the fire. For example, operational weather models use grid spacings on the order of several kilometers, whereas the fire front may be a mere 10 meters in depth and would require centimeter-scale resolution for a high-quality LES. Our goal is to move systematically from manual refinement in multilevel embedded mesh methods to fully adaptive mesh calculations within the FDS framework. Along the way LES quality measures specific to fire will be developed.
