when simulating 2D airfoils co ordinates for aerodynamic optimization studies, at the end of ICEM cfd shows the following error.

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

when importing the the formatted co ordinates points in icem cfd, leading edge has for gaps in the curve and i draw the line to connect it. i followed this video and applied on the airfoil are SD7062, SD6060 and e387. all the airfoil has gaps.

Kindly give suggestion to rectify my problem

Hi,

this warning is very clear.
There are edges which are boundary edges and are not (corrrectly) associated to a curve.
What i do to find such erros i do the following:
# Convert the structured to unstructred
# in the Mesh tree, hide all elements except line elements.

That way you should see where are the gaps. Then make sure that all edges of that area are connected to the boundary curves.
In some specific cases this is not enough. In that case make some screenshots and document your problem in detail.

With regards,
Sebastian

I have attached the file. Still i could not identify any kind of discontinuities in the airfoil
