Within the Advanced Simulation and Computing (ASC) program, the Integrated Codes area develops and improves predictive simulation tools to support U.S. stockpile stewardship. These large-scale codes incorporate physics and engineering models and specialized codes to predict, with reduced uncertainty, the behavior of weapons and their components in a variety of...

The Physics & Engineering Models program provides the models and databases used in simulations supporting the U.S. stockpile. These models and databases describe a large variety of physical and engineering processes that occur during the operation of a nuclear weapon. In addition to supporting the stockpile, a number of other...

Partnerships among the national laboratories, industry, and academia leverage a broad spectrum of talent and multiply the effectiveness of our research efforts. These collaborations help solve the challenges of developing computing platforms and simulation tools across a number of disciplines. Computer Science Research Institute The Computer Science Research Institute brings...

The Verification and Validation (V&V) program conducts two major activities at Sandia. The first is to perform assessments and studies that quantify confidence in Advanced Simulation and Computing (ASC) calculation results. The second activity develops and improves V&V and uncertainty quantification methods, metrics, and standards. Assessments This project area conducts...
