Event Description: 

The intent of this presentation is to provide an introduction to aspects of my work in the shock multiphysics department at Sandia related to the ALEGRA code and to specifically call out instances where undergraduate students have contributed to this work. I will give an overview of the shock multiphysics modeling approach in ALEGRA and discuss the practical drivers and organizational principles for effective development and user impact. Areas to be mentioned include the classical Lagrangian-Eulerian algorithm, magnetohydrodynamic discretizations, electromechanics, effective choices for model equations and a user friendly approach to enabling sampling based meta-analysis using Dakota. In the process I will also describe several instances where undergraduate students have been effective partners and why.

My experiences with ALEGRA development influence my view on what is required to move current next-generation prototype modeling tools to production status. This presentation will give insight to faculty and students of the broad scope of potential collaborative opportunities at Sandia and a view of how computational algorithm and tool development may provide support to difficult and important problems of national and international scope.
