Defense Applications

We develop and apply multiphysics analysis tools that address various issues important to the DOE, DoD, DHS, and other U.S. Government agencies, and support production use of our codes by our principal customers. Our ALEGRA multiphysics code (http://www.cs.sandia.gov/ALEGRA/Alegra_Home.html), employs an Arbitrary Lagrangian-Eulerian (ALE) methodology targeted at the simulation of high strain rate, magnetohydrodynamic, electromechanic and high energy density physics phenomena. It is a C++ multi-material finite element code based on a large displacement fomulation designed to accurately model strong shock behavior.
