We have worked on several projects aimed at improving the efficiency and understanding of multiscale methods, especially those applicable to problems involving atomistic-to-continuum coupling. Activities include blending methods for AtC coupling and efficient quasi-continuum methods for problems with long-range interactions.
We review the results obtained under grant support. Details are given in the publications listed at the end of the review. We also provide lists of the personnel funded by the grant and of other collaborators on grant-related research and of the talks delivered, also under grant related research. We collaborated closely with geophysicists at the Los Alamos National Laboratory and the National Center for Atmospheric Research; especially noteworthy is our collaboration with Todd Ringler of LANL who was an active partner on much of our work.
The work reported is in pursuit of these goals: high-quality unstructured, non-uniform Voronoi and Delaunay grids; improved finite element and finite volume discretization schemes; and improved finite element and finite volume discretization schemes. These are sought for application to spherical and three-dimensional applications suitable for ocean, atmosphere, ice-sheet, and other climate modeling applications.
Abstract Not Provided
The use of a sensitivity equation method to computer derivatives for optimization based design algorithms are discussed. The problem of designing an optimal forebody simulator is used to motivate the algorithm and to illustrate the basic ideas. Finally, how an existing computational fluid dynamics (CFD) code can be modified to compute sensitivities and a numerical example is presented.
