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

The idea behind the tutorial is to provide a quick introduction to many features in VisIt. Note that the VisIt Class, which is much more thorough, can be found here.
