The cover illustration shows an unstructured symmetry plane surf ace grid and tetrahedral fie1d cut for a NASA Space Shuttle Orbiter configuration. The complete volume grid contains 547,741 nodes and 3,026,562 tetrahedral elements and was used for an inviscid CFD analysis. The geometry preparation and grid generation work were performed by David L. Marcum and J. Adam Gainther using SolidMesh with AFLR volume and surf ace generators at the MSU/NSF Engineering Research Center for Computational Field Simulation at Mississippi State University.
