Welcome to the home page for the Center for Simulation of Dynamic Response of Materials, one of the five university centers in the Academic Strategic Alliance Program of the NNSA's Advanced Simulation and Computing program (ASC).

The image featured above is a frame generated from a recent VTF run on LLNL's IBM SP3, frost. The mesh is 16800x11200 and is distributed over 320 CPUs. The picture shows a diffracting detonation around a corner, depicted by the blue rectangle. The red line is the locus of 95% reaction completion. The detonation leaves the small channel (top-left) as a plane wave and finds a larger reservoir. At this late stage in the simulation, a first re-ignition event has developed in a full transverse detonation wave that is reflecting from the corner wall (left), leving jets of high-temperature products. A second re-ignition event can be observed in the top-right corner. (M. Arienti and J.E. Shepherd. A numerical study of detonation diffraction. J. Fluid Mech., 529:117 - 146, 2005.

The ASC Center for Simulation of Dynamic Response of Materials is based at the California Institute of Technology under U. S. Department of Energy contract W-7405-ENG-48.
