Customers, team, & goals

• Customers: Argonne NEAMS personnel, especially INCITE awardee Paul Fischer

• VACET team members: Hank Childs & Christoph Garth– Activity normally leveraged by NEAMS vis $’s

• Goal: ensure visualization and analysis needs continued to be met successfully and analysis aid in advanced analysis.

This work depends on efficient streamline

generation (described in later talks)We needed parallel efficient

streamline techniques to do this work. (SC09)

Streamlines with astrophysics data

• Upcoming analysis: use streamlines to study flow through the center of the star and better understand how neutrinos get irradiated.
