Development of the automated grid overset approach implemented within the PEGASUS 5 code was supported by the High-Lift Subelement of the NASA Advanced Subsonic Technology / Integrated Wing Design Program. The technical point of contact was Dr. Karlin Roth at NASA Ames Research Center. Additional project support was provided by the Aeroscience and Flight Mechanics division at NASA Johnson Space Center.
