Slide title: Quantum-to-Atomistic-to-Continuum Simulations

Slide image: The slide shows three images of brittle fracture that increase in magnification and detail from left to right. The images come from a presentation entitled, "Billion-atom Multiscale Simulations of Nanosystems on a Grid."

The left image, labeled "Finite Element" by the researchers, shows brittle fracture modeled on the continuum scale.

The center image, labeled "Molecular Dynamics" by the researchers, is an enlargement of the end of the brittle fracture and shows modeling on the molecular scale.

The right image, labeled "Density Functional" by the researchers, is, in turn, an enlargement of the very tip of the brittle fracture and depicts modeling on the electron scale.
