Simulations of Dynamo Action in M-Dwarf Stars

A recent paper by researchers at the University of Colorado, Boulder shows that new global magnetohydrodynamic simulations of rapidly rotating M-Dwarf stars, run on NAS supercomputers, produced convective nests. This previously unseen phenomena might contribute to the formation of persistant active longitudes scientists have observed on the Sun and other stars. The Boulder team's related work was highlighted as a NASA@SC21 research project.

NAS Division Experts Add GPU Support to USGS Earthquake Modeling Code

NAS Division experts are working with researchers at the U.S. Geological Survey (USGS) to assess potential benefits of running their Cascading Adaptive Transitional Metropolis in Parallel (CATMIP) application on GPU nodes. In tests, the code ran more than 20 times faster on GPUs than on traditional CPU-only nodes. CATMIP is used to model and study earthquake faults.

Predicting Orion Launch Abort Acoustics

François Cadieux, NASA Ames Research Center

This seminar will discuss a campaign of CFD scale-resolving simulations undertaken by the Launch Ascent and Vehicle Aerodynamics (LAVA) team to analyze and predict vibrational loads on the Orion crew capsule during an abort scenario.

Cutting-edge Simulations Help Predict Water Operations in the SLS Launch Environment

To help keep ignition overpressure waves from damaging the Space Launch System during launch, fluid dynamics engineer Travis Rivord at NASA’s Marshall Space Flight Center runs simulations of the solid rocket booster plume-water induced environment. In this short video presentation, Rivord discusses both the challenges of simulating the launch environment physics—using the Pleiades supercomputer at NAS—and his team’s successful validation of various test scenarios.

When Water is Coming from All Sides

Researchers at the National Oceanographic and Atmospheric Administration teamed up with colleagues at the Virginia Institute of Marine Science at William & Mary to develop and test the world's first three-dimensional operational storm surge model. The research was enabled by supercomputers at the NASA Advanced Supercomputing facility and the Texas Advanced Computing Center.
