It is desirable when designing new planetary probe architectures or planning for the use of an existing design to rely on computational predictions of vehicle performance, in addition to, wind tunnel and flight data. Essential aspects to
assure the accuracy and reliability of these solutions are the selection of the grid topology, grid resolution, and grid quality. This publication presents an integrated planetary probe design framework that automatically generates grids for planetary probes given the geometry of the vehicle and the entry trajectory flight conditions. In addition, the framework links the entry trajectory interface to CFD modeling codes via the automatic grid generation capability.
