With extensive support from Ames and NYU personnel, researchers in the DOE's Adaptive Dispersion Modeling Project have developed a new toolset that enables multiple order-or-magnitude improvement in the time required to the generate computational meshes needed for aerosol dispersion modeling within urban cityscapes. In tests with a model of downtown Salt Lake City, the new tools generated complex, high-resolution grid in minutes-nearly a 5000-fold improvement over their original process, which took almost a week to produce a comparable grid. The team has integrated the surface modeling and volume mesh modules from Cart3D (NASA's 2002 Software of the Year) into the DOE's analysis suite. The new toolset is being incorporated into improved modeling codes within the DOE, through the Department of Homeland Security's Advanced Scientific Computing Research and Development Program.
