Simulations

Left shows galaxies from AREPO simulation, right shows actual galaxies from Hubble image (...

A new approach for simulating the birth and evolution of galaxies and cosmic filaments within the Universe has been developed by researchers at the Harvard-Smithsonian Center for Astrophysics together with their colleagues at the Heidelberg Institute for Theoretical Studies. It's called AREPO, and has been used to simulate the evolution of our Universe from only 380,000 years after the Big Bang to the present. The full variety of spiral, elliptical, peculiar, and dwarf galaxies appear in the simulated Universe.  Read More

Scientists destroy simulated Earths to better understand exoplanets, such as Earth-like pl...

Unlike in old B movies, real scientists don’t scream “Fools! I’ll destroy them all!” before throwing the switch on their doomsday device. At least, most of the them don’t. However, the August 10 issue of the Astrophysical Journal reports that a team of scientists are working on destroying the world - not once, but repeatedly. Fortunately, the world they’re destroying exists only in a computer simulation and its destruction is in the service of learning more about planets revolving around other stars.  Read More

A free-surface simulation of the forces experienced when diving helped in the design of Sp...

A controversy during the 2008 Beijing Summer Olympics was Speedo's introduction of its drag reducing LZR Racer swimming outfit. The suit worked so well that it was subsequently outlawed by the Fédération Internationale de Natation (FINA) as the technological equivalent of doping - it gave too large an advantage. Now, with the help of ANSYS simulation software, and just in time for the 2012 London Summer Olympics, Speedo has introduced the Fastskin3 racing system, which offers a new and apparently legal approach to drag reduction during competitive swimming.  Read More

Physicists at the National Institute of Standards and Technology (NIST) have built a quantum simulator that contains hundreds of qubits - quite a jump from the the 2-8 qubits found in state-of-the-art digital quantum computers. The simulator has passed a series of important benchmarking tests and scientists are poised to study problems in material science that are impossible to model using classical computers.  Read More

The TL1 and its 180 degree display

What happens when you bring together cutting edge gaming technology and a legendary automotive company? The answer is one of the most powerful home racing simulators money can buy, the TL1. Motion Simulation has joined forces with the U.K. automaker behind the Ariel Atom, creating a simulator in a class of its own, featuring near panoramic projectors, and a custom built racing cockpit designed in conjunction with the experts from Ariel.  Read More

Air traffic controller and pilot James Price has spent $150,000 and the last 12 years buil...

Like many computer users of my generation, I've notched up many hours of virtual flight time in a number of fairly realistic simulation programs. There are those who are simply not satisfied with keyboard, mouse and joystick control of jet fighters and passenger airplanes on a desktop computer system, though. Air traffic controller and pilot James Price is one such simulation-junkie who has taken his desire for realism to dizzy new heights by having the nose lopped off a veteran Boeing 737, fitting out the gutted cockpit with working controls, dials and monitors and then interfacing the hardware with flight simulation software. It's been a labor of love but we think the result is well worth the enormous amount of time and effort that's gone into the build.  Read More

Sandia's Z-Accelerator in action (Photo: Sandia National Laboratories)

In the beginning, there was the thermonuclear bomb - mankind had harnessed the energy of the Sun. Confident predictions abounded that fusion reactors would be providing power "too cheap to meter" within ten years. Sixty years later many observers are beginning to wonder if billions of dollars of effort has been lost in digging out dry wells. Now a new simulation study carried out at Sandia National Laboratories in Albuquerque, New Mexico, suggests that magnetized inertial fusion (MIF) experiments could be retrofitted to existing pulsed-power facilities to obtain fusion break-even.  Read More

The OVO-4 is a full-motion, fully-enclosed light aircraft flight simulator, that can be yo...

Chances are, you will never get to try out the new 3D MiG flight simulator. If you have almost US$60,000 that has nothing better to do, however, you can now buy something almost as impressive – the OVO-4 Home Flight Simulator. The egg-shaped capsule contains a full simulated light aircraft cockpit, with three linked 24-inch monitors displaying the output of Microsoft’s Flight Simulator X. Best of all, however, the capsule pitches and rolls according to what’s happening in the simulation – users presumably have to supply their own barf bags.  Read More

Russian Aircraft Company's MiG-29

Russian Aircraft Company's MiG is best known for its fighter planes which have been used by the USSR, China, North Korea and North Vietnam since the beginning of WWII. These days, the former Government-owned RAC MiG is a publicly traded entity and competes on the open market with its technologies, having more than 1600 of its MiG-29 fighters in operation in 25 countries. Now MiG is claiming a major first in military aviation with the launch of a 3D flight simulator at the Dubai Air Show, providing volumetric visualization of beyond-the-cockpit space for trainee top guns. The simulator comes complete with the MiG-29’s cockpit and actual control systems.  Read More

A high resolution slice of the whole 250Mpc box of Bolshoi (Made by Stefan Gottlober (AIP)...

The Bolshoi cosmological simulation is by far the most ambitious project of its kind. It harnesses the power of supercomputing to bring cosmology into the realm of experimental sciences. Based on observable input data, the Bolshoi simulation allows scientists to see what the higher structure of our universe might have looked like at particular points in time throughout its formation, arming them with tools that should make cracking the mysteries of dark matter, dark energy and galaxy formation much more feasible.  Read More
