Stockpile Stewardship Science
Providing high confidence in the safety, security, reliability, and effectiveness of the U.S. nuclear weapons stockpile that forms the foundation of annual assessments of stockpiled weapons and their certification.

About the Cover
Simulation of a hydrodynamic instability computed with the BLAST high-order finite-element code using the Vulcan supercomputer at Lawrence Livermore. This problem tests the ability of a code to propagate shock waves over multiple-material regions and handle complex mesh vortex-induced motion. The high-order algorithms enable resolving the physics at much higher fidelity and efficiency than is possible with traditional second-order algorithms. The shape arises from the fact that the shock travels faster in lower-density regions, resulting in natural vortex motion at the point where three shock waves meet. Work was supported by the LDRD project “Scalable High-Order Computational Multiphysics at Extreme Scale” (14-SI-002).
