These meshes were generated with GridTool/VGrid at Cessna. Grid is in mm. Note: Gridtool restart file (dlrf11_config2_vgrid_family.rst) is included. ----------------------------------------------------------------------------------- !!!!!NOTE: It was discovered (late) that the D fine grid was made with incorrect min spacing at walls. It should have been 0.00024, but it was mistakenly created with the medium grid spacing of 0.00037. This was corrected after the workshop on 3/14/2014 (by e.lee-rausch@nasa.gov); see corrected files in ../CorrectedGrid directory. ----------------------------------------------------------------------------------- File Types Provided: 1. VGRID type (see VGRID_FILE_FORMATS.txt) .cogsg .bc .mapbc_vgrid (if used, this file extension may need to be renamed .mapbc) .poin1 2. CGNS type (includes all grid, connectivity, and BC information) .cgns = CGNS file (see www.cgns.org) (file conversion from original Vgrid files was done by C. Rumsey... c.l.rumsey@nasa.gov) 3. AFLR3 type .b8.ugrid = AFLR3 file (unformatted, big-endian, contains no record marks (ACCESS="STREAM") write(2) nnodesg, ntface, nqface, ntet, npyr, nprz, nhex write(2) (x(i),y(i),z(i),i=1,nnodesg), & ((if2nt(j,i),j=1,3),i=1,ntface), & ((if2nq(j,i),j=1,4),i=1,nqface), & (ifacetag(i),i=1,ntface+nqface), & ((ic2nt(j,i),j=1,4),i=1,ntet), & ((ic2np(j,i),j=1,5),i=1,npyr), & ((ic2nz(j,i),j=1,6),i=1,nprz), & ((ic2nh(j,i),j=1,8),i=1,nhex) (see: http://www.simcenter.msstate.edu/docs/solidmesh/ugridformat.html) nnodesg = number of nodes ntface = number of boundary triangles nqface = number of boundary quads ntet = number of volume TETRA_4 elements npyr = number of volume PYRA_5 elements nprz = number of volume PENTA_6 elements nhex = number of volume HEXA_8 elements x,y,z = grid coordinates if2nt = face-to-node pointers for boundary triangles if2nq = face-to-node pointers for boundary quads ifacetag = surface ID number for each boundary face (1, 2,... , number of BCs) ic2nt = cell-to-node pointers for TETRA_4 elements ic2np = cell-to-node pointers for PYRA_5 elements ic2nz = cell-to-node pointers for PENTA_6 elements ic2nh = cell-to-node pointers for HEXA_8 elements .mapbc_aflr= BC file describing the boundary condition for each surface ID (in this file we are using: 6662=y-symmetry, 5000=farfield, 4000=body) (file conversion by C. Rumsey) (if used, this file extension may need to be renamed .mapbc) Note: large files have been gzipped nodes = 75,806,896 elements = 446,989,442 (all tets) boundary elements = 3,400,312 (all tris) NOTE: There is a y shift of approximately 0.01 mm the surface geometry. Independent tests were made to verify the effect of this shift is negligible.
