When the space shuttle Columbia disintegrated on re-entry in 2002, sophisticated computer models were key to determining what happened. A piece of foam flew off at launch and hit a tile, damaging the leading edge of the shuttle wing and exposing the underlying structure. Temperatures soared to thousands of degrees as Columbia plunged toward Earth at 27 times the speed of sound, said Gallis, who used NASA codes and Icarus for simulations...

A relic from long before the age of supercomputers, the 169-year-old math strategy called the Jacobi iterative method is widely dismissed today as too slow to be useful. But thanks to a curious, numbers-savvy engineering student and his professor, it may soon get a new lease on life.
Engineers and scientists from Pipistrel utilized HPC and technical computing resources to design and develop the Taurus G4 aircraft. The aircraft was conceived, designed and built in a mere 5 months, relying heavily on CAD and rapid prototyping techniques, but especially on the use of CFD and other computer aerodynamic tools for evaluation of flight performance and handling before committing to the building of the prototype.
The return of supersonic passenger travel may be coming closer to reality thanks to NASA’s efforts to define a new standard for low sonic booms. Several NASA researchers will present their work at Aviation 2014, an annual event of the American Institute of Aeronautics and Astronautics. They will share with the global aviation community the progress they are making in overcoming some of the biggest hurdles to supersonic passenger travel.
Engineering turbomachines that routinely punch past the sound barrier will require more brain than brawn. In fact, it will take more than a thousand-trillion calculations per second on the nation’s most powerful supercomputer to simulate the precise design spaces and complex fluid dynamics that affect machine performance.
Mudslides. Landslides. Volcanic debris flows. Avalanches. Falling rocks... They can come along so suddenly that people, homes, roads and even towns are buried or destroyed without much warning. Recently, we've had dramatic reminders of this, such as the mudslide in Oso, WA, where 41 people died; an avalanche on Mt. Everest that killed 13 experienced Sherpas and another landslide event in Jackson, WY.
