Experience
Curtis Ober received his B.S. (1989) and M.S. (1990) from New Mexico State University in Mechanical Engineering, and worked on his Ph.D. (1994) on the aerodynamics of bodies in a supersonic wake at the University of Texas at Austin and the Institute of Advanced Technology. After graduation, he started work at Sandia and began work in seismic imaging. This work was part of a collaboration with the oil and gas industry which included IBM, SGI, Intel, Conoco, Amerada Hess, ARCO, Fairfield Industries, Kerr-McGee, PGS, GX Technologies, and the University of Texas at Dallas. This work produced the Salvo seismic imaging software, which is still in use and generating royalties. In 1999, the Salvo project won an R&D 100 Award as one of the 100 most technologically significant new products of the year.
In 2000, Curt began working as the principal investigator on the Premo compressible fluid flow project, which built on the SIERRA framework. The Premo project is developing capabilities to simulate compressible flows around transonic, supersonic and hypersonic bodies in flight. This unstructured, finite-volume, software has several solvers (Runge-Kutta, Newton-Krylov and Point-Implicit schemes). Curt has been working on several capabilities for the Premo project: arbitrary body motion, time-integration schemes, boundary conditions, overset meshes, and segregated-physics solvers.
