WARNING: Mesh has uncovered edges. ANSYS Fluent needs a complete boundary (lines in 2D) or it will give a variety of errors and not read in the mesh! If this was 2D Hexa, perhaps your edges are not associated with perimeter curves
This is a U-shaped tunnel, there is a cylinder in the middle.
I've checked edge associations and I think my boundary is complete, but still get this warining. ICEM.PNG
As a result, I cannot import the mesh into Fluent.Fluent.PNG
Here is my ICEM file, Hope you guys can help me! Thank!

this problem has been reported countless times.

And also the solution:

Check all boundary associations. All.

Use the check mesh feature.

For a 2d case i prefer to do this: blank all mesh elements but the line elements.
This way you will see which boundary hasn't been converted to unstructured, or which wasn't meshed.

With regards,
