Advanced techniques produce highly realistic simulations of fluid dynamics.
The researchers compared the computer vision simulation they developed with photos from the Mount St. Helens explosion. Credit: University of California, San Diego Computer scientists at the University of California, San Diego have developed a method to generate highly realistic computer-generated images of the fluid dynamics of elements such as smoke. The research, conducted by the Visual Computing Center at…

Decoding the effects of gravitational waves on the atmosphere using high-resolution climate simulations
As seen from the International Space Station, when humid air encounters an imbalance in air density, gravitational waves appear over Lake Superior, causing the airflow to oscillate up and down. Credit: NASA/ISS Researchers from Stanford University, the European Center for Medium-Range Weather Forecasts (ECMWF), and Oak Ridge National Laboratory are conducting a summit at the institute’s Summit to better understand…

Improved spin-density correlation simulations give researchers clearer insight into neutron stars
Neutrinos travel through a gas of neutrons and are sensitive to the correlation between the spin and density of the neutronic material. These correlations determine how much energy is transferred from the neutrino to the neutron. Credit: Dean Lee When a star dies in a supernova, its remains can become a neutron star. Inside a neutron star, protons and electrons…
