HPC Enhancement of Plume Modeling for Use by Military Simulators

An application programming interface (API) was developed to make CT-Analyst's high fidelity physics based plume predictions available to modeling and simulation (M&S) tools. This plume API was used with the M&S application one semi-automated forces (OneSAF). OneSAF is a next generation entity level simulation. For a 10 by 5 km region of Baghdad, OneSAF made use of CT-Analyst through the application programming interface (API) to determine the plume locations, the plume concentration at points within the simulation, and to determine the attenuation of visibility along a line. Before the simulation is run, FAST3D-CT generates a pre-computed Nomograf database. During the simulation, OneSAF calls a CT-Analyst process that in turn interprets the Nomograf database to generate plumes.
