It is possible to create a named selection by selecting faces  that belong to different geometrical bodies. However, upon import into Fluent, the named selection is fragmented and the boundary condition needs to be employed on each of the faces. This process can be cumbersome if the number of faces in a given named selection are large.   To avoid this segmentation, in addition to creating a named selection for the required faces, the bodies to which these faces belong also need to be grouped into another named selection. As a result, when the mesh is imported into Fluent, the bodies that are now in the named selection are treated as a single cell zone. Consequently, the boundary faces that were part of the named selection are not segmented, and so  the boundary condition needs to be employed only one face zone.
