His research interests include subgrid-scale models and numerical methods for large-eddy simulation, adaptive mesh refinement, immersed boundary methods, and Lagrangian particle methods.
The Fire Dynamics Simulator, in various forms, has been under development for almost 25 years. However, the publicly released software has only existed since 2000. While many individuals have contributed to the development of the model and its validation, a smaller group is actually responsible for writing the computer program. The FDS Technical Reference Guide contains an extensive list of model contributors. Here, however, we recognize those individuals who have done the actual programming. Originally, the basic hydrodynamic solver was designed by Ronald Rehm and Howard Baum with programming help from Darcy Barnett, Dan Lozier and Hai Tang of the Computing and Applied Mathematics Laboratory (CAML) at NIST, and Dan Corley of the Building and Fire Research Laboratory (BFRL). Jim Sims of CAML developed the original visualization software. The direct pressure solver was written by Roland Sweet of the National Center for Atmospheric Research (NCAR), Boulder, Colorado. Kevin Mc-Grattan expanded the basic program to include fire-specific routines, and he remains the custodian of the FDS source code. Glenn Forney developed the companion visualization program Smokeview and remains its custodian. Kuldeep Prasad added the multiple-mesh data structures, paving the way for parallel processing. William (Ruddy) Mell has added special routines to extend the model into areas such as microgravity combustion and wildland fire spread. Charles Bouldin devised the basic framework of the parallel version of the code. Jason Floyd, a former NIST Post-Doc, wrote the mixture fraction and droplet evaporation routines. Simo Hostikka, a NIST guest researcher from VTT Building and Transport, Finland, wrote the radiation solver and the char pyrolysis routine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
