  1. AstroBEAR 2.0AMR Multi-physics for Astrophysics and HED Lab AstrophysicsAdam FrankUniversity of Rochester Jonathan Carroll Martin Huarte-Espinosa Shule Li (H) Eddie Hanson (H) Erica Kaminski (H) • Alexi Poludnenko (UNL) • Tom Gardiner (LANL) • Kris Yirak(LANL) • Andy Cunningham (LLNL)

  2. UR/LLE Collaboration: Impact • HEDLA 2012 • ~75 talks in all fields • 9 talks UR Astro/LLE collaboration (12%) • 5 students/post-docs from A. Frank group (7%) • AstroBEAR used at • UNC • Rice • JPL/UCLA* • Heidelberg • UM • RIT

  3. AB 2.0: Parallel AMR PerformanceCarroll, Shroyer, Frank & Ding 2012 JCP • Rebuild Parallel Architecture • distributed tree/threading • Load balance AMR grid hierarchy

  4. Disk Formation In Binary Stars • Wind from primary captured by secondary • Bondi-Hoyle Accretion

  5. Magnetized Shocked Clumps(Li et al 2012) • MHD Heterogeneous flows = critical problem • ALL studies to date use “external linear fields” • New study: embeds self-consistent fields in clumps • Toroidal • Poloidal • “Turbulent”

  6. Future Directions Li, Frank & Blackman 2012 Anisotropic Heat Conduction • Refine parallel peformance (N ~ 104 processors) • Continue HEDLA/Astrophysics studies • Disks/Jets/Ionization Fronts/Turbulence • Broaden user base • LLE/AstroBEAR partnership • Heat Conduction
