Meshing problem using ICEM CFD
 

I am new in CFD and now working on meshing a multi element aerofoil. In ICEM CFD I have done mesh successfully. But. when I try to open it in Fluent it shows an error. It gives cell coordinate and tells no face is created. I do not know what to do.

If it is 2d problem, then it must on the x-y plane with z= 0

it is a 2D problem and z=0.
