PROBLEM SOLVED
Hello dear friends.
I have encountered a problem with output mesh in ICEM.
I have a room with an inlet and outlet when I mesh the domain with unstructured option provided in ICEM ther is no problem as in pictur 1. you can see both inlet/outlet in picture.
but when I use blocking and mesh the domain the in let and out let are not in the output mesh as in picture 3.
I have also tried to mesh half of domain structure and the other half unstructured but in the structured half the outlet is not in output mesh picture 2 and picture 4 is the output mesh in fluent.

what is wrong with structured blocking mesh that does not include inlet/outlet in output mesh?
I have made material point as fluid in every domain I wanted to mesh.

I have associated the block edges to the curves of outlet .the problem is solved

Sorry, I am not sure what you mean in your second post... In case the problem is not fixed:

This is most likely an issue with association between the block face and the surface.

If you were relying on auto association (default which usually works), perhaps you have some duplicate surfaces and it is simply projecting to the wrong one. You can force it by associating face to surface. Pick the face and the part you want it to associate with.
