  1. Fusion Update 2010 • Allen R. Sanderson • SCI Institute • University of Utah www.vacet.org

  2. Fusion SAP • Three years • Utah, ORNL, and LBNL • Support common analysis and visualizations needs with fusion • Particle Analysis and Visualization (integration of fastbit for query based analysis) • Magnetic Island Analysis and Visualization • Comparative Visualization (Experiment to Simulation and Simulation to Simulation) www.vacet.org

  3. Particles Analysis and Visualization • Goal • To supply tools to facilitate the study the affects of turbulence on the trapping state and radial diffusion of particles. Outward radial diffusion is heat transport which is bad. • Deployed 1.12.2 • Querying based visualization • Hardening integration of Fastbit into VisIt. • Converters and indexing tools for GTC and XGC Data • Readers – H5Part and HDUF • Hardening of VisIt to supper Queries and Particles • Interface for Persistent Particals • Two remaining efforts • Interface for query selection • Cumulative queries www.vacet.org

  4. Magnetic Island Analysis and Visualization • Goal • Visualizing the magnetic field topology is necessary to the understanding how the plasma energy is deposited on the material wall. Energy (i.e. heat) on the wall is bad. • Deployed 1.12.2 • Topological analysis of the magnetic field • Hardening of streamline code • Ability to continue streamline integration • Ability to add additional seeds • Hardening of analysis code • Adaptive streamline length • Addition of more robust O point detection • Integration of M3D C1 Elements • Ability to visualize scalar/vector data • Construct Poincaré plots. www.vacet.org

  7. Comparative Visualization Cont. • Experiment to Simulation • Synthetic diagnostics • Experimental Data stored in MDSplus • Ability to get not only data but physical geometry • Requires MDSplus interface within VisIt • Ability perform integration of simulation data. • Use cases might require custom queries. www.vacet.org
