Medium-level grids (as interpreted by the grid authors) for JSM with pylon/nacelle. There are two versions of the grids; one with a wake refinement zone (_withwake) and one without (_nowake). Created with StarCCM+ no wake: 239,948,270 nodes; 62,511,015 cells with wake: 250,604,557 nodes; 64,146,223 cells ccm = StarCCM format cgns = CGNS format NOTE: the author's original naming of the actual grids has been retained. However, please note that these grids are globally referred to as: "a-JSM_UnstrPolyhedral_ANSA+StarCCM" for the purpose of the workshop. Contact: Marie Denison marie.f.denison@nasa.gov
