Numerical Analysis and Applications

Applied mathematics and numerical analysis provides a key foundation to Sandia’s success in applying advanced computing to solve national-scale problems. Such work includes development of new numerical discretizations that are provably stable and convergent for multi-physics problems as well as algorithms and tools for mathematical optimization in the presence of uncertainty that enable critical decisions to be made based on the results of computer simulation. In each case, these methods are developed with a keen awareness of the underlying mathematics and are applied to a wide range of energy, geoscience, climate and national security applications.
