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, […]

Sandian Re-Elected as President of the Association for Computing Machinery Special Interest Group on Graphics and Interactive Techniques

Jeff Jortner (in Sandia’s Scalable Modeling & Analysis Systems Dept.) has been re-elected for another three-year term as the President of the Association for Computing Machinery (ACM) Special Interest Group on Graphics and Interactive Techniques (SIGGRAPH). ACM is the world’s largest educational and scientific comput­ing society and delivers resources that advance computing as a science […]

Wind Generator Modeling

Sandia finalized and submitted the updated “WECC Wind Power Plant Dynamic Model­ing Guide” and the “WECC PV Power Plant Dynamic Modeling Guide” to the Technical Studies Subcommittee at the Western Elec­tricity Coordinating Council (WECC). These dynamic modeling guides present the second-generation generic models as speci­fied in the January 23, 2014 WECC report. The WECC generic […]

Widespread Hydrogen Fueling Infrastructure Is the Goal of H2FIRST Project

As hydrogen (H2) fuel cell electric vehicles (HFCEVs) continue to roll out in increasing numbers, the infrastructure for fueling them must expand as well. To this end, a new project launched by EERE’s Fuel Cell Technologies Office and led by Sandia and the National Renewable Energy Laboratory (NREL) will work in support of H2USA, the […]

Federal Electric Regulatory Commission Revised Its Small Generator Interconnection Procedure and Small Generator Interconnection Agreement

After two years of industry consultation, the Federal Electric Regulatory Commission (FERC) has issued a final ruling on the much anticipated modification of the FERC Small Generator Interconnection Procedure (SGIP) which governs the interconnection of small generators (smaller than 20 MW) that sell wholesale electricity. The SGIP also serves as a template for state rules that […]
