New Software to Support Interest in Extreme Science

03.05.2011
Today the University of Chicago's Flash Center for Computational Science will release a major new version of supercomputer code, called FLASH 4-alpha. Based on previous software for simulating exploding stars, this is the first version of the FLASH code that has extensive capabilities for simulating high-energy density physics experiments.

The U.S. Department of Energy's National Nuclear Security Administration Advanced Simulation and Computing Program has funded the addition of the new capabilities to this software, which will help scientists at universities across the nation better understand the fundamental properties of matter at high densities and high temperatures.

"The enhanced FLASH code is an open toolset for designing and analyzing experiments that address questions about the nature of planetary interiors, the creation of elements via nuclear processes, and how matter behaves in violent shocks and other extreme conditions," said Don Lamb, Flash Center director and the Robert A. Millikan Distinguished Service Professor in Astronomy & Astrophysics at UChicago.

The code will support academic HEDP research at a variety of laboratories, including major national facilities such as the National Ignition Facility at Lawrence Livermore National Laboratory in California, the Z machine at Sandia National Laboratories in New Mexico and the Omega Laser Facility at the University of Rochester.

"These facilities use extremely powerful lasers or large amounts of electric current to generate conditions that allow scientists to investigate and address important issues in areas such as astrophysics, material science, planetary science and fusion energy," said Milad Fatenejad, a Flash Center research scientist. "Simulations play a vital role in demonstrating the viability of proposed experiments and analyzing experimental results. The enhanced FLASH code will be able to fill both of these roles."

The Flash Center is already using the new capabilities in FLASH to simulate radiative shock experiments conducted by the Center for Radiative Shock Hydrodynamics at the University of Michigan and at the Omega Laser Facility, said Fatenejad.

LLNL and other laboratories have developed highly capable codes for in-house research in HEDP, Lamb said. "Unlike FLASH, these codes were never designed with the academic community in mind," he said. "Having a workhorse open toolset for scientists at universities is absolutely essential, and until now has not existed."

The addition of new HEDP capabilities in the FLASH code has benefited from a collaboration the Flash Center has initiated with scientists at the universities of Michigan and Wisconsin, and at Los Alamos National Laboratory and Lawrence Livermore National Laboratory.

"We are very excited about the science these new capabilities will make possible," said Flash Center associate director Anshu Dubey. "The Center has been able to add HEDP capabilities to the FLASH code and make it run efficiently on the next generation of computers thanks to a decade of funding by the DOE NNSA ASC

Academic Strategic Alliance Program and recent funding by the DOE Office of Advanced Scientific Computing Research, as well as access to the world's fastest computers through the NNSA ASC Program and the Office of Science INCITE Program."

The new software is a collaboration between the Center, the University's Computation Institute and Argonne National Laboratory. DOE funding for the initiative is through the Argonne Institute for Computing in Science.

More than 700 scientists worldwide have used FLASH code, and they have published more than 400 papers reporting results based on its use. Although most of these scientists have used FLASH for astrophysical research, others have modified it for simulating atmospheric physics and biological processes. IBM, NVIDIA and other companies have also licensed FLASH to test and develop hardware and software.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
