This directory contains the NASA Structured Oveset grid family 3, level D: This level D grid has been UPDATED as of 04/19/2021 (the original structured overset RANS mesh level D had an unnecessary split in the fuselage component grid, not present in grids 3.A-C, so it was decided to regenerate this level to ensure all structured meshes were as consistent as possible). Original D grid had 296 zones instead of 295, with zones 1&2 of size 549x173x153 New D grid has 295 zones, with the first one of size 1091x173x153 *p3d - grid file INTOUT* and XINTOUT* - connectivity files *bc - boundary condition file *cgns - cgns version of *p3d file (gridpoints only - no BC or overset info included) For more details, see the README file one level above. Note: large files are gzipped. NOTE THAT THESE GRIDS HAVE BEEN CREATED IN METERS, NOT INCHES.
