Sandians Participate in 46th Annual American Geophysical Union (AGU) Conference

Fifty-six Sandians from ten Centers joined more than 22,000 geoscience professionals, students, and academics at the December AGU Fall Meeting. Sandia staff chaired multiple technical sessions and gave dozens of presentations on topics ranging from improved climate models to performance models for underground waste storage to 3D printing and digital rock physics. Marianne Walck (Director […]

NASA Award for Marginal Ice Zone Observations and Process Experiment (MIZOPEX)

Sandians Mark Ivey and Darin Desilets (both in Sandia’s Geophysics and Atmospheric Sciences Dept.) were included in a NASA Group Achievement Award “for outstanding achievement in executing the MIZOPEX using multiple classes of unmanned aircraft [UASs].” The MIZOPEX campaign used DOE’s Sandia-managed Oliktok Point, Alaska, facilities to investigate unique UAS capabilities, combined with in situ sensing […]

Sandia Team Attends World Water Week in Stockholm

Stephanie Kuzio, Vince Tidwell, and Tom Lowry (all from Sandia’s Earth Systems Analysis Dept.), represented Sandia’s Water and Environment Program (part of the Sandia’s Climate & Environment Program Area) at World Water Week in Stockholm August 31–September 5th. The theme for this year’s conference was Energy and Water, and Vince Tidwell was invited to speak […]

Sandians Published in American Chemical Society’s Environmental Science & Technology

Vince Tidwell and Barbie Moreland (both in Sandia’s Earth Systems Analysis Dept.) and Katie Zemlick recently published “Geographic Footprint of Electricity Use for Water Services in the Western U.S.” in Environmental Science & Technology. A significant fraction of our nation’s electricity use goes to lift, convey, and treat water, while the resulting expenditures on electricity […]

Parallel Implementation of Smoothed-Particle Hydrodynamics Method Using LAMMPS/Trilinos

Sandia has implemented a scalable parallel capability to model polarized-fluid dynamics in micro devices driven by an electric potential. The Sandia team discretized the mathematical model (Navier-Stokes and Poisson-Bolzman equations) with an implicit smoothed-particle hydrodynamics (SPH) method. Due to the method’s particle nature, the team used the LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) particle library, […]
