The attack takes place at the climax of the blockbuster Avatar: Rockets slam into the Pandora inhabitants’ homeland tree. Explosions, flames and thick clouds of smoke appear on the screen. To keep the audience pinned to the edge of their seats, the images must be realistic. But the simulation of physical processes is especially tough to implement. This includes representation of liquids and gasses, which fall into the category of fluids.
Some of the most prized violins in the world were crafted in the Italian workshops of Amati, Stradivari and Guarneri — master violinmaking families from the 17th and 18th centuries who produced increasingly powerful instruments in the renaissance and baroque musical eras. These violins, worth millions of dollars today, represent the Cremonese period — what is now considered the golden age of violinmaking.
Visual-Environment 10.0 is a comprehensive simulation platform designed to enable the swift integration of calculations using the open source CFD modules of OpenFOAM. It allows engineers to accelerate preparation of most common CFD calculations, including airflow for external aerodynamics, internal airflow for underhood and climate control, and investigation of flow around rotating bodies.
Unlike in mathematics, it is rare to have exact solutions to physics problems. The first exact solution that describes a system expanding at relativistic velocities radially and longitudinally has been presented by researchers. It applies to a wide array of physics contexts and will help to better model galactic structure, supernova explosions and high-energy particle collisions, such as those studied at the Large Hadron Collider at CERN.
At a White House ceremony on November 20, 2014, President Obama presented the National Medal of Science and National Medal of Technology and Innovation to individuals who have made outstanding contributions to science and engineering. The awards are the nation's highest honors for achievement and leadership in advancing the fields of science and technology.
Researchers from NCSU conducted innovative research that will allow better prediction of thermal hydraulic behavior for current and future nuclear reactor designs.
The noise generated by civil air transport adversely impacts population centers near major airports. With the expected growth in air travel, community exposure to aircraft noise will increase considerably. To alleviate this problem, the Environmentally Responsible Aviation (ERA) project within NASA's Aeronautics Mission Research Directorate is working to simultaneously reduce aircraft noise, fuel consumption, and engine emissions.
Researchers used HPC resources were utilized to run and visualize a breakthrough simulation involving a long-track EF5 tornado embedded within a supercell.
Robo Brain — a large-scale computational system that learns from publicly available Internet resources — is currently downloading and processing about 1 billion images, 120,000 YouTube videos, and 100 million how-to documents and appliance manuals. The information is being translated and stored in a robot-friendly format that robots will be able to draw on when they need it.
Pointwise 17.2 R2 eponymous computational fluid dynamics (CFD) meshing software provides the ability to rapidly generate layers of hexahedral cells. Near-wall and near-wake hex layer generation capability is part of T-Rex (anisotropic tetrahedral extrusion), one of Pointwise's hybrid meshing techniques.
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...

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.
