This may be a simple fix, but I haven't been able to get my mesh to import into Fluent. I have three different meshes (same geometry but different mesh count and refinement levels all file type .cgns) but none of them upload correctly with the error: Warning no nodes read. When I open the meshes in a free meshing program Gmsh I am able to view the meshes. Even when I export them from Gmsh as a .msh file they still fail to import into Fluent. Thanks for the help.

Hello,
To import the mesh file correctly into Fluent in .cgns format, you need to first import the mesh using the mesh only option and set up boundary conditions. Then select appropriate model and read the data using the data only option. Hope this solves the issue. Thanks!
