Skipping zone air_inlet (not referenced by grid)

I'm trying to make very simple geometry in Gambit. The column with small air inlet in the bottom. The problem is with the bottom of course. I use cylinder (column) and circle (air inlet) at the bottom face. Everything is meshed and exported to file.msh. Then loading it to the Fluent I got the message "Skipping zone air_inlet (not referenced by grid)". So that circle at the bottom face is deleted - it is not visible by Fluent.

What am I making wrong?

Thanks in advance Maciej

Re: Skipping zone air_inlet (not referenced by gri
Sounds like a connectivity problem. Go back to gambit and check if your air inlet circle is connected with the bottom of your column. There is a connectivity button somewhere in the lower right corner of gambit. Turn it on and the small air inlet circle should turn to pink if everything is all right. If its blue then you havent it connected properly.

I am facing the same problem as Maciej. My inlet was not referenced by grid when loaded into fluent as well. When i check, it IS in pink but the problem persists. Could there be another reason or something i missed? Thanks!

I think if you change your mesh to another type of mesh, this problem will be solved.

I don't understand this. What to connect (edges? faces? volumes?) and how (unite? merge? or something else?)?

For me- changing Mesh type between Tet/Hex helped.

To the skipping problem
As I was looking for what has been wrong, I found that my mesh has been not written completely in Gambit, so the non-written part of the mesh will be skipped in the fluent though there has been boundary condition you set there.

Wish you good luck~
