[edit] Abstract

Visualization is an essential component of the scientific discovery process. Scientists and businesses running HPC simulations leverage visualization tools for data exploration, quantitative analysis, visual debugging, and communication of results. This half-day tutorial will provide attendees with a practical introduction to mesh-based HPC visualization using VisIt, an open source parallel scientific visualization and data analysis platform. We will provide a foundation in basic HPC visualization practices and couple this with hands-on experience creating visualizations.

This tutorial includes:

  1. An introduction to visualization techniques for mesh-based simulations.
  2. A guided tour of VisIt.
  3. Hands on demonstrations of end-to-end visualizations of two a fluid simulations:
    • An Aneurism (Blood Flow) Simulation
    • A Water Flow Simulation

[edit] SC12 Tutorial

Presented at SC2012 (Room 251-F) on Monday November 12, 2012 using VisIt 2.5.2.

We are presenting a full day tutorial. The morning focuses on introductory and intermediate content and the afternoon on advanced usage. If you cannot attend both sessions, please feel free to attend either session.

[edit] Abstract

VisIt is a free interactive parallel visualization and graphical analysis tool for scientific data. Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations. VisIt contains a rich set of visualization features so data can be viewed in a variety of ways. The Advanced VisIt Usage tutorial shows the casual VisIt user how to more effectively use the software for visualization, presentation, and data analysis in order to enable discovery and communication. Topics covered include methods for comparing multiple simulation outputs, coupling VisIt and a simulation in situ, advanced Python scripting, movie-making, queries, and data selections. Alternate plotting representations such as Scatter plots, Parallel Coordinate plots, Material plots, and Molecule plots are also covered. Tutorial attendees are assumed to have prior experience using VisIt or other visualization software.
