Notes:

Large Scale Simulation

Crestone Project TeamóUnclassified visualization from a simulation that supported a hydrodynamic validation experiment

EnSight visualization software used to generate image (adaptive mesh lower center region)

Pressure variation in the imploding shockwaveóblue to red increasing pressure

LANL/LLNL completed: first full-system 3D simulations of explosion, largest computer simulation attempted

ASCI white machineóboth teams used different approaches, LANLóover 122 days CPU time, LLNL over 39 days to execute

Simulations completed over two months ahead of schedule
