Hi,everyone.
I have a problem with meshing by ICEM CFD.

I'm blocking a 2D geometry in ICEM and then meshing & converting it to uns mesh, but when i try to export it for ansysFluent one error as follow appear.

"child killed: SIGABRT

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".

I associated curves to edges several time,but this error appeared again.
I try too much to solve this problem,but i can't.
Please told me how i can solve this problem.
The attachment files are as follows.

Thanks for any help.
