I am trying to use a fan boundary on an internal boundary but when I transfer the mesh to fluent the internal boundary isn't showing up under the boundary tree.
I have assigned the boundary a name in the named selection and it shows up in the mesh so I am not sure why it isn't coming up in the conversion.
The geometry is really simple. It's just a 2D disk inside a 3D rectangular domain. There is an additional cylinder surface running through the domain to help with meshing controls (This is named wake). The 2D disk, named AD, is the boundary that isn't showing up. I used share topology for the component. Oddly the wake is showing up.
The AD isn't showing up but weirdly the internal fluid is.

It's a surface in Meshing, so won't be recognised by Fluent: Fluent only sees the "solid" volumes. The way I do it is to split the volume up with face(s) so the fan is part of the solid.

"interior-fluid" is the facet ID for all of the volume cells. Displaying that tends to end badly if you have a high cell count as the graphics tends to fall over!

Fab thanks so much. But shouldn't affect running the simulation in any way?

No, it's supposed to be there, and no longer in the display list to avoid people trying to plot contours on it.
