Computing codes, simulations helped make ignition possible
Part 6 in a series of articles describing the elements of Lawrence Livermore National Laboratory's fusion breakthrough. For Lawrence Livermore National Laboratory (LLNL) physicist George Zimmerman, and for the hundreds of physicists, computer scientists and code developers who have worked on fusion for decades, computer simulations have been inexorably tied to the quest…
Computational Engineering is key to ignition success
In a room illuminated by blinking lights and glowing monitors, more than 2,000 synchronized computers are triggered to run 5 million lines of code. The intricate code language is responsible for aligning and firing 192 laser beams — and carrying some 800 channels of target diagnostic data — efficiently and reliably several times a day. This isn’t a scene from a science…

High-fidelity simulation offers insight into 2013 Chelyabinsk meteor
On the morning of Feb. 15, 2013, a small asteroid exploded over Chelyabinsk, Russia, sending a loud shockwave and sonic boom across the region, damaging buildings and leaving around 1,200 people injured. The resulting meteor, with a diameter of approximate 20 meters (roughly the size of a six-story building), was one of the largest to be detected breaking up in the Earth’s…

LLNL physicist probes causes of life-shortening 'dwell fatigue' in titanium
"Dwell fatigue" is a phenomenon that can occur in titanium alloys when held under stress, such as a jet engine's fan disc during takeoff. This peculiar failure mode can initiate microscopic cracks that drastically reduce a component's lifetime. The most widely used titanium alloy, Ti-6Al-4V, was not believed to exhibit dwell fatigue before the 2017 Air France Flight 066…
