Visualization and Analysis of Magnetic Fusion Simulations In this application talk, which is an on going collaboration between Computer Scientists and Plasma Physicists, I will discuss some of the techniques we have developed for visualizing and analyzing magnetic fusion simulations. For instance, in many fusion simulation codes, the identification of instabilities in the plasma flow is critical to understanding the nature of tokamak experiment design. Because the plasma equilibrates much more rapidly parallel to the magnetic field lines than perpendicular to the magnetic field lines, visualizing the magnetic field topology is necessary to the understanding how the plasma energy is deposited on the material wall. At the same time the magnetic field deforms, the plasma becomes turbulent which causes particles in the plasma to radially diffuse causing further energy to be deposited on the wall of the tokamak. Querying and understanding the particles that diffuse is another critical need in the development of fusion reactors. To address these needs I will discuss our team's approach to not only developing but also delivering topological analysis and query based visualization tools to application scientists. Biography Allen Sanderson is a Research Scientist at the Scientific Computing and Imaging Institute at the University Of Utah. Before coming to the U he was a Senior Software Engineer at Evans and Sutherland Computer Crop. where he was part of a team that developed software for military and commercial flight simulators. He obtained his his Bachelors in Mechanical Engineering from Oregon State in 1985 and his Masters in BioEngineering and Ph.D in Computer Science from the University of Utah and was a Chateaubriand Fellow at INRIA in Sophia Antipolis, France.
