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).
