Hi, everyone:
I suffered a serious problem about CGNS files.
I have a mesh file with CGNS format, but while I launched the SU2_CFD, an error occurred :

!!! Error !!!
Mesh_1.cgns is not a CGNS file.
Now exiting...

The mesh file is generated from salome platform, the version of libcgns l is 3.2.1, I configured the SU2 with CGNS correctly. Can anyone help me with this error? Every suggestion is expected!

Hey LeeJearl,

There are a few options that you have to make sure to hit in order for your CGNS mesh to work.

% Mesh input file
MESH_FILENAME= mesh.cgns
%
% Mesh input file format (SU2, CGNS, NETCDF_ASCII)
MESH_FORMAT= CGNS

If you can't find these options or are still getting errors please upload the config file and the mesh and I will take a look.

Best,

David

LeeJearl,

One more thing to check is if your installation of SU2 is able to run the CGNS test case (https://github.com/su2code/SU2/wiki/...personic-Wedge). If this goes well you should check if you can open your mesh in ADF viewer inside of the CGNS tools to make sure you don't have compatibility issues.

Best,

David

Hi, David:
Thank you for your reply, I think the problem must caused by the hdf5, the SU2 build with not hdf5, but my CGNS file based hdf5 library.
