Answers in Milliseconds
CT-Analyst provides accurate, instantaneous, 3D predictions of chemical, biological, & radiological (CBR) agent transport in urban settings. In the past, more accuracy has always meant more computing and more computing means more delay. Waiting even a fraction of a minute for a simplified scenario computation can be far too long for timely situational assessments. Therefore, CT-Analyst uses the best computations possible prepared well ahead of time and captures their salient results in a highly compressed database to be manipulated and displayed instantly.
The CT-Analyst product can provide answers in approximately 0.05 seconds versus computational fluid dynamics models which can take one to two hours to run per scenario. CT-Analyst also provides more detailed information, quicker, and with better results than industry accepted “Puff/Plume” models that take several minutes to run.
Take a Brief Look at CT-Analyst
An instantaneous crisis management system called CT-Analyst, based on detailed urban aerodynamics computations using Large Eddy Simulation (LES), has been developed, tested, and deployed to evaluate wind borne Contaminant Transport (CT) threats and to aid in time-critical civil defense decisions in cities, where current transport and dispersion methods are too slow and inaccurate. Designed for the military prior to 9/11, CT-Analyst can incorporate verbal reports, handle input from fixed and mobile sensors, and functions in realistic emergencies where the nature, amount, and location of an airborne contaminant source or Chemical, Biological, Radiological (CBR) agent is unknown and where the wind fields are dynamic and complicated by the city geometry. CT-Analyst is well suited to urban and site defense in the Homeland Security context.
Real-Time Airborne Contaminant Prediction
Toxic gas releases in urban areas are controlled by urban aerodynamics (not meteorology) with very complex geometries, unsteady buoyant flows, buildings that shed vortices high above the ground, dynamic turbulence, and wind gusts.
The crucial operational issue is to keep computational fluid dynamics accuracy while computing with sufficient speed for real-time emergency assessment.
CT-Analyst works by using pre-computed detailed urban geometry and flow based on computational fluid dynamics and then post-processing the compressed simulation results instantly for users.
CT-Analyst Will Save Lives
Three fourths of direct exposure fatalities trace their origin to the first 15 minutes of an event. If effective response begins in three to five minutes, 85% of these fatalities can be avoided. CT-Analyst allows users in the field and at operational nerve centers to work together, using the same data to effectively monitor and adjust planning and logistics as information is gathered or updated.
CT-Analyst allows those analyzing a CBR scenario to view exposed and soon-to-be exposed regions based on very limited data.
CT-Analyst allows emergency management personnel to instantaneously project optimal evacuation paths based on the current evolving situation assessment.
