  1. 10,5603 grid Inertial confinement fusion (ICF) calculation with multifluid PPM • Rendered 13,688 frames at 2048x1080 pixels4 panels per view & 2 views per stereo image @ 4096x2160 pixels. • Stereo movie is 1711 frames Here we compare the time required to generate the movie of our trillion-cell ICF simulation with the multifluid PPM code, performed in Dec., 2012. Rendering the movie using Blue Waters’ GPU nodes produces a movie in one day that would otherwise take a month and a half of continuous data transfer and image rendering at Minnesota.

  2. Here we see image 1000 of the movie of 1711 frames. This is one eye’s view, and the image has 4096x2160 pixels. We are looking at the mixing fraction between ICF capsule material and the enclosed fuel in a simplified numerical experiment where both materials are represented by ideal, monatomic gases. Pure fluids of either type are transparent. As the concentration by volume of dense capsule gas increases, colors go from dark blue, through aqua, white, yellow, to red. We see the central portion of the simulation volume.

  3. Here we zoom in to get a better view. We have in this simulation so much grid resolution that it is hard to do it justice on a video projector with only 1.25 Mpixels. The mixing fraction shown here is one of the most important quantities produced in the simulation. Mining this data quantitatively will help us to validate statistical models of the mixing process in such an unstable, converging flow.
