Grids are AFLR .b8.ugrid format. v3-coarse-0tail.b8.ugrid is the coarse grid, 0 degree tail v3-coarse-fine-0tail.b8.ugrid.gz is the coarse grid with a refined fuselage, 0 degree tail v3-med-0tail.b8.ugrid is the medium grid, 0 degree tail v3-medfine-0tail-usurf.b8.ugrid.gz is the medium grid with a refined fuselage, 0 degree tail v3-fine-0tail.b8.ugrid is the fine grid, 0 degree tail v3-fine-notail.b8.ugrid.gz is the fine grid, no tail v3-fine-2uptail.b8.ugrid.gz is the fine grid, ih-2 tail v3-fine-2dwntail.b8.ugrid.gz is the fine grid, ih+2 tail v3-xfine-0tail.b8.ugrid is the extra fine grid, 0 degree tail v3-med-notail.b8.ugrid is the medium grid, no tail v3-med-2dwntail.b8.ugrid is the medium grid, ih+2 tail v3-med-2uptail.b8.ugrid is the medium grid, ih-2 tail ------------------------------------------------------ ******BEST PRACTICE GRIDS*************** A set of grids was generated using aflr settings more in-line with our "best practices." These grids have a fixed first off-the-wall cell size of 0.0001". The wing/tail surface grids are identical to their above mentioned counterpart grids. On the coarse and medium grid we have refined the fuselage spacing to be closer to the resolution used on the fine grid. Only the zero tail grids are included in the "best practice" grids. Description of file names(all grids are zero tail angle): v3-coarse-fine.b8.ugrid : This is the coarse best practice grid with a fuselage spacing similar to the fine grid v3-medfine.b8.ugrid : This is the medium best practice grid with a fuselage spacing similar to the fine grid v3-fine.b8.ugrid : This is the fine best practice grid v3-exfine.b8.ugrid : This is the extra fine best practice grid ************************************************************************ For questions, contact Chad Winkler, 314-233-9437 chad.m.winkler@boeing.com or Mori Mani mori.mani@boeing.com
