Center for Computing Research

Computational Mathematics, 01442

The Computational Mathematics Department (1442) performs cutting edge research, driven by DOE needs, to develop the mathematical foundations and the algorithmic and software advances to enable accurate, predictive, and scalable computational simulation methods. We deliver comprehensive theoretical and computational tools that impact Sandia’s mission and push our capabilities beyond forward simulations. Members of the department interact and collaborate with a broad range of Sandia and DOE staff and also maintain a highly visible external research presence by collaborating with universities and industry, publishing peer-reviewed literature, participating in professional societies, and refereeing and editing for journals.

    Mini-symposium on ice sheet modeling

    At the SIAM CSE conference, a two part mini-symposium on Ice Sheet Modeling was organized by Sandians Luca Bertagna, Mauro Perego (1442) and Irina Tezaur (8759) along with Daniel Martin from LBNL. The mini-symposium focused on theoretical and computational advancements in ice sheet modeling, addressing many of the mathematical and computational challenges arising when modeling the dynamics of large ice sheets for computing projections of sea level rise. During the two lively sessions, a variety of topics were addressed by the speakers, including mesh adaptation, coupling of ice sheets and ocean, iceberg mélange and Bayesian inference. Bertagna, Hansen and Perego from SNL gave talks related to DOE’s PISCEES and FASTMath SciDAC projects.
