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 specializes in applied scientific computing and our core competency is computational physics and engineering. 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, as well as environmental and meteorological modeling.
  • Engineering systems analysis for energy-research and -manufacturing systems, 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.
  • Development of parallel discrete-event-simulation (DES) algorithms and numerical engines for network, traffic, social dynamics, sensor, and organization simulations.
  • 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, the interdiction of smuggled nuclear materials, and remote sensor networks.

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.
