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 try too much to solve this problem,but i can't.
Please told me how i can solve this problem.


Thanks.

Ok. I have also met this problem in the 2d mesh. I fixed it by using Check Mesh tools.
ICEM will ask you if to delete some edges, so then choose ignore option. I hope it helps.

I have associated every curve to edge around my boundary multiple times however this still has not resolved the error.

when I look at the "lines" of my mesh I notice that not all of the lines around my boundary have been included. However, I have associated the edge to curve for these parts and ICEM confirms the association but I still have the same error.

I have looked at the "check mesh" which highlights a number of cells, however nothing has been resolved when I clock "fix".

Please help.
