ALEGRA Code Versions

The ALEGRA family of multi-physics codes, including ALEGRA, ALEGRA-MHD, ALEGRA-HEDP and ALEGRA-EMMA, is developed upon the Nevada framework and a selection of highly-specialized, separately-supported libraries. ALEGRA codes operate well on numerous platforms in both serial and parallel modes. The codes use internally-generated computational grids (inline mesh) or external mesh generation tools (e.g. CUBIT).

ALEGRA is a multimaterial ALE (Arbitrary Lagrangian-Eulerian) finite element code that models large distortions and shock propagation in multiple materials.

ALEGRA-MHD models resistive magnetohydrodynamics including magneto-solid mechanics. ALEGRA-MHD magnetic field diffusion and the magnetic forces exerted on materials in motion.

ALEGRA-HEDP adds ion-electron temperature and radiation transport to ALEGRA-MHD physics to provide a modeling capability for high energy density physics applications.

ALEGRA-EMMA combines solid dynamic material response with the quasi-static electric field approximation to model capacitive electromechanical systems.

Nevada provides the underlying software infrastructure and third-party library management for the ALEGRA family of codes.

The ALEGRA family codes operate successfully on single to very large scale capacity multiple-processor computers.
