"Grand Challenge" simulation on ASC Purple
in support of the National Ignition Campaign

 

Simulation of the  grain structure of a beryllium-copper tamper for a fusion ignition capsule in the presence of  a NIF laser energy drive


Simulation of the grain structure of a beryllium-–copper tamper for a fusion ignition capsule in the presence of a National Ignition Facility (NIF) laser energy drive. Scientists at LLNL have been studying the grain structure of the tamper material and its significance as a source for initiation of turbulent instabilities in the capsules. The blue regions show where the beryllium–copper has melted, and the other colors represent grain orientations for the still-solid tamper. This simulation ran on the ASC Purple supercomputer with over one billion total zones, making it one of the largest continuum material simulations ever done at Livermore.
