Multiscale Modeling

By its nature, multi-scale modeling is highly interdisciplinary. It has evolved independently across many fields, because a broad range of scientific and engineering problems involve multiple scales. Even though multi-scale problems are extremely difficult we are making progress. Inter-discipline communication difficulties, however, are rampant. Even though circulatory physiology and oceanography deal with currents and flows, many findings remain confined to the disciplines in which they were first studied. Much of this has to do with scale differences, but different groups think in different jargons. The overarching question again is how does one reliably compute larger reliable coarse scales while at the same time accurately modeling the net effect smaller events and structures have at subgrid-sized scales in both materials and fluids?
