Researchers produce an animation of 9/11 - WTC North Tower


80 hours of high-performance computing produced an engineering analysis of that three-quarters-second that it took an airplane to tear through the World Trade Center north tower.

Although most Americans believe they know what brought down the World Trade Center twin towers on Sept. 11, 2001, civil engineers are still seeking answers to questions that could save lives in the future.

Structural engineers need to know from a scientific perspective what happened to the buildings during the terrorist attacks in order to prevent future failures. The search for answers continues with the help of a state-of-the-art animated visualization created by researchers at Purdue University.

The simulation depicts how a plane tore through several stories of the World Trade Center north tower within a half-second and found that the weight of the fuel acted like a flash flood of flaming liquid, knocking out essential structural columns within the building and removing fireproofing insulation from other support structures.

To develop the new animated visualization, Voicu Popescu, an assistant professor of computer science, developed a translator application that creates a link between computer simulations and computer visualization systems to automatically translate simulation data into a 3-D animation scene.

The animation can be seen online.
