[Gmsh] Error when exporting to .CGNS : Duplicate child name found: Patch_0001

[Blais, Bruno]

Hello everyone,

I have been using gmsh for quite a while now, but never with the CGNS file format. Whenever I try to export as a CGNS, I get a weird error:

Error detected by CGNS library
Duplicate child name found: Patch_0001 (where Patch_0001 is the name of a boundary condition group I selected)

This problem is intermittent, sometimes it does not happen when the mesh is coarser or finer. When I visualize the result in cgnsview, I can clearly see that one point (or node) is missing on the boundary condition on which the error appeared. I tried to look online and on this mailing list and I could not find an answer to this issue. I know the CGNS exporter is in Alpha (since a large while it seems) and is not officially supported, but I was wondering if any of you had a solution.

Best regards,
BB
