   Jun 1999 — Present

   Develop state-of-the-art software for structured grid generation, for computational fluid dynamics applications in hypersonics. Some of these codes are freely available to US citizens. The Three-Dimensional Advanced Grid Generation System (3DMAGGS), and the Volume Grid Manipulator (VGM) are two such codes. Software was also developed for the Tecplot visualization software from Tecplot Inc. including macros and addons. Recent work was completed on the evaluation of a design for the inlet of a hypersonic flight vehicle three times the size of the X-43A, with an eye on a vehicle for space access missions at NASA. Additionally, combine grid generation experience with the ability to perform hypersonic flow field computations, numerous NASA missions have been supported, including the Space Shuttle Orbiter, Orion Crew Exploration Vehicle, Mars probes, Galileo, and Magellan.
