Application

Laser back scatter modeling by Dr. Steve Langer at LLNL

Technology

  • Ability to view data using a client/server architecture
  • Ability to interactively set transfer function to bring out features of interest at key points in the simulation
  • Ability to quickly generate side-by-side animations of key physics quantities to understand time dependent behavior

Result/Impact

  • Client/server architecture allows the user to view his data on his desktop without moving the data
  • Ability to interactively set transfer function allows scientist to quickly explore data
  • Automated movie generation makes it easy for the user to see time evolution of data with different views and transfer functions.

Challenges

  • Extreme data size generated by high resolution simulation (220 billion cells)
  • Correlating multiple, complex, 3d phenomenon over time

Note:

The most common type of fusion reaction discussed for fusion energy in the near future is the fusion of two hydrogen isotopes: deuterium (2H) and tritium (3H).  NIF – national ignition facility.
