About Engineering

Animation Computational Electromagnetics (EMSolve) Computational Fluid Dynamics Methods Development Group "Stochastic Engine" Systems and Decision Sciences Related Link Institute for Terascale Simulation				LLNL's computational engineering community is among the best in the world at solving very large, nonlinear, structural and electromagnetic applications. Our engineering analysts benefit from the substantial expertise residing in areas of code development, numerical methods, parallel processing, and constitutive behavior of materials. Over the past two decades, the structures community in particular has established a reputation for being at the leading edge of solving difficult applications in weapon assessment, DOD applications, and industry applications. The complexity and scale of emerging programmatic needs continue to drive our innovation in development and the resulting uniqueness of our fielded tools.
		A roadmap was established to set priorities for investments in coupled structural, electromagnetic, and computational fluid dynamics (CFD) code capabilities. Current activities range from tools to design the next generation of mixed-signal chips (systems on a chip) to full-scale analysis of key DOE and DOD systems to design capabilities for microfluidic and photonic devices. There is no area of technology that contributes more broadly than computational engineering to the new Science and Technology thrusts of the Laboratory, as well as its core weapons mission.
