In the Chemical, Biological, Radiological-Nuclear and Explosives Research and Technology Initiative (CRTI) Project 09-509TD, a persistent, highly realistic, game-based synthetic environment (SE) for incident commanders and first responders to conduct individual and/or team training and collaboration (at the tactical and/or strategic levels) to address deliberate or accidental Chemical, Biological, Radiological, Nuclear and Explosives (CBRNE) releases in an urban environment has been proposed. This will be achieved by integrating a state-of-the-science physics-based urban flow/dispersion modeling system and a high-fidelity building-aware Geographic Information System (GIS) representation of a real cityscape (The City of Calgary) with a proven game-based simulation engine developed by 3DInternet Inc. WATCFD is responsible for the provision of hazardous plume entities to the game-based simulation engine. The objective of this report is to provide a technical description of modeling and simulation of the highly disturbed building-induced flow field in downtown Calgary and the transport and dispersion of hazardous agents released into this complex flow field using the computational fluid dynamics (CFD) model urbanSTREAM, which consists of 1) generation of a structured computational grid from a building database for an urban landscape in the form of an Arc View Shape file for the City of Calgary; 2) generation of highly disturbed building-aware flow fields in the urban environment
