If you have any questions about these data files, please contact the person listed in the table. The CGNS Committee is not able to provide technical support for the data files listed on this webpage.
Please post any CGNS data files (along with a graphic file if possible)
or the URL of the datafiles which you would like to
share with the CGNS users community at
cgnstalk.
Most of the files on this page are very old and hence are ADF type. However, a few have been converted to HDF5, as noted (using cgns_type.f tool on Utilities Page).
