Abstract
- ALEGRA is a multiphysics finite-element shock hydrodynamics code, under development at Sandia National Laboratories since 1990. Fully coupled multiphysics capabilities include transient magnetics, magnetohydrodynamics, electromechanics, and radiation transport. ALEGRA is used to study hypervelocity impact, pulsed power devices, and radiation effects. The breadth of physics represented in ALEGRA is outlined here, along with simulated results for a selected hypervelocity impact experiment. • ALEGRA is a multiphysics finite-element shock hydrodynamics code. • An ALEGRA simulation captures phenomenology from a previous gas gun experiment. • Multiphysics capabilities include electromagnetics and radiation transport. • A multiphysics simulation demonstrates electromagnetic induction during impact.
