HIRENASD Unstructured Grids - VGRID software

Published by Dashlink | National Aeronautics and Space Administration | Metadata Last Checked: August 04, 2025 | Last Modified: 2025-03-31
These grids were constructed using VGRID software from NASA Langley. The grids designed for node based (labeled 'nc') and cell-centered solvers are supplied. Grids with mixed elements (labeled 'mixed') and tetrahedral elements (labeled 'tets') are supplied. Each mixed elements tar-file contains grid in aflr3 .ugrid format and the corresponding .cgns file. Each tetrahedral elements tar-file contains grid in native VGRID format (.cogsg, .bs, .mapbc) and the corresponding .cgns file. Some files were too large and had to be split into parts. To combine the parts, use cat filename_part1 filename_part2 > filename. Grids are in units of 'mm'. Information about grids, that is number of nodes, elements, etc., is provided in AePW_HIRENASD_Grid_Statistics_VGRID.docx Please report any issues with these grids to Pawel.Chwalowski@nasa.gov Please note that the final grids for Aeroelastic Prediction Workshop are due on November 1. Therefore these grids still may change based on your initial calculations. Soon, the mode shapes from NASTRAN interpolated on the surface mesh will be provided for above grids. Happy Computing!
