Computational
Shock & Multiphysics
Sandia’s Computational Shock & Multiphysics Department provides unique, state-of-the-art modeling and simulation capabilities using coupled multiphysics and multiple discretization technologies to simulate high strain rate and high energy density physics for the U.S. defense and energy programs. To accomplish this objective, we conduct an active program of research and development in computational shock physics and methods, produce high-performance application codes that address relevant issues important to the DOE, DoD, DHS, and other U.S. Government agencies, and support production use of our codes by our principal customers.

A Three-Dimensional Resistive MagnetoHydroDynamics (MHD) option has been implemented
in the Sandia ALEGRA code and is being used to simulate z-pinch wire array implosions at a level of detail never before attempted. ALEGRA is being developed as part of the ASC Applications
program, and uses the Nevada finite element code framework. The 3D MHD modeling capability in ALEGRA is crucial for understanding the instabilities that occur in z-pinch wire array implosions,
which in turn are critical phenomena in determining the resulting radiation pulse generated in the Z machine. |
