When exporting CGNS files from Ansys Fluent, does it export the mesh info as well or just the data?
The Ansys Fluent User Guide states that: "CGNS (CFD general notation system) is a single file (for example, file.cgns) containing coordinates, connectivity, zone information, velocity, and selected scalars."
So the binary CGNS files that Ansys Fluent exports includes the mesh information.
