POC: David M. Hetrick (865)576-7556/ Scientific Computing Within the ORNL Modeling and Simulation Group The ORNL Modeling and Simulation Group (MSG) develops sophisticated numerical solutions for a wide range of scientific, engineering, and operational applications. MSG's core competency is computational physics and engineering, and we specialize in multi-disciplined computational sciences; that is, integrating basic sciences and their appropriate numerical methods with individual problem physics. Within our analysis focus areas, our unique combination of scientific staff, modeling and simulation (M&S) expertise, and state-of-the-art computing resources permit us to address essentially any application, to any level of numerical sophistication, at any point in the R&D-Design-Operations spectrum. These world class M&S capabilities include the following.

Physics-based modeling including computational fluid dynamics (CFD), numerical heat conduction, computational fracture mechanics, computational physics, physiological and psychological biomedical simulation, and environmental modeling.

Engineering systems analysis for industrial process and facilities-vulnerability assessments.

Analysis of complex systems such as human neurological and physiological processes, human cognition, highly coupled system-of-systems, and autonomous process-control systems.

Numerical physics such as optimization, probabilistic analysis, and inverse calculations.

A diverse set of applications including research reactors, global carbon sequestration, fusion energy, nuclear weapons manufacturing, advanced military weapons systems, pollutant fate and transport, medical- and industrial-event forewarning, autonomous measurement and control systems, energy infrastructures, and the interdiction of smuggled nuclear materials.

These applied scientific computing capabilities represent an extremely versatile M&S resource for a broad range of R&D, industrial, homeland defense, and military applications. We welcome the opportunity to discuss your potential applications and ways MSG can contribute to a solution.
