Abstract : This research program has emphasized innovative computations and theory that support and enhance each other. A coherent approach was used that depends upon abstracting important mathematical concepts and computational methods from individual applications to a wide range of applications involving complex continua, including wave refractions, flows in elastic and plastic media, and complex fluid mixing. Adaptive computational methods were developed for flows with discontinuities and were implemented on modern parallel computers.
