Whenever I try to export as a CGNS, I get a weird error:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Error detected by CGNS library<o:p></o:p></p><p class=MsoNormal>Duplicate child name found: Patch_0001 (where Patch_0001 is the name of a boundary condition group I selected)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>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.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Best regards,<o:p></o:p></p><p class=MsoNormal>BB<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span lang=FR-CA style='mso-fareast-language:EN-CA'>-----<o:p></o:p></span></b></p><p class=MsoNormal><b><span lang=FR-CA style='mso-fareast-language:EN-CA'>Bruno Blais, M.
