Multiscale modeling and simulation are used in scientific and engineering research in biology and the health sciences, materials and processing sciences, and earth and atmospheric sciences. This emerging integrated, computational approach can lead to better understanding, analysis, and quantitative predictions of the behavior of realistic, complex systems. Multiscale modeling and simulation links atomic-scale phenomena with macroscopic responses over time scales relevant to humans (from minutes to centuries) by establishing rigorous links between widely different theoretical formalisms and computational methods that capture a very broad range of space and time scales—from electronic, molecular, and mesoscopic or microstructural scales to continuum or macroscopic scales.

The core capabilities of multiscale modeling and simulation include computational quantum mechanics, statistical mechanics, and continuum mechanics combined with applied and computational mathematics, such as numerical analysis, nonlinear analysis of dynamic systems, optimization, and control theory. Some of these methods, which have been developed over many decades, are quite mature. However, the rigorous coupling of these methods to produce predictive models of phenomena that span multiple length and time scales remains a significant challenge. Examples range from linking molecular phenomena, such as DNA transcription and gene expression, with cellular, tissue, and organ response to connecting atomic-scale and grain-scale dynamics with the macroscopic response of engineering materials, such as metals, semiconductors, and polymers.

The ultimate goal of multiscale modeling and simulation is to produce a global framework for system-level analyses of processes and phenomena relevant to human scales that are governed by phenomena occurring at much finer length and time scales.

Achieving this goal will require advances in coupling various time and length scales, as well as in mathematics, computer science, and computational science. This session focuses on the state of the art in several aspects of multiscale modeling and simulation, including the coupling of modeling and simulation methods across time and length scales for specific applications in the science and processing of engineered materials (e.g., semiconductors, metals, and polymers) and in biology and health science. Presentations address recent advances in the theoretical, mathematical, and computer science underpinnings of multiscale modeling, as well as computational science challenges, such as tera- and peta-scale computing, advanced visualization, and enabling technologies.

This volume includes 14 papers from the National Academy of Engineering's Tenth Annual U.S. Frontiers of Engineering Symposium held in September 2004. The U.S. Frontiers meeting brings together 100 outstanding engineers (ages 30-45) to learn from their peers and discuss leading-edge technologies in a range of fields. The 2004 symposium covered these four areas: engineering for extreme environments, designer materials, multiscale modeling, and engineering and entertainment. Papers in the book cover topics such as scalable mobile robots for deployment in polar climates, the challenges of landing on Mars, thin-film active materials, vascular tissue engineering, small-scale processes and large-scale simulations of the climate system, simulating physically accurate illumination in computer graphics, and designing socially intelligent robots, among others. Appendixes include information about the contributors, the symposium program, and a list of the meeting participants. The book is the tenth in a series covering the topics of the U.S. Frontiers of Engineering meetings.
