[Gmsh] Problem with volume creation in 3D geometry

Hello to all gmsh developers and many thanks for this flexible
open-source mesh creation software, expanding possibilities for finite
I am using the latest version of gmsh software for windows, in order to
construct the 3D geometry of a transformer.
I am attaching you the respective geo file (GMSH_Transformer.geo)
consisting of 10 volumes (elementary entities
3,4,5,6,1142,1381,1621,1860,2100, corresponding to physical volumes
2107,2108,2109,2110,2101,2102,2103,2104,2105 and 2106, respectively)
representing the cores and coils of the active part. These volumes are
surrounded by external surfaces consisting of curved (rounded) and
rectangular parts, representing the geometry of the tank with its
corrugated panels. Although each part of the external surfaces seems to
be well defined (and can be selected during the 'Elementary
Entitities-->Add--->New--->Volume' process), it is impossible to create
the volume between these outer surfaces and the rest of the volumes in
the considered geometry.
Can anybody provide some hint on possible errors in the geometry
definition? Why, although the outer surfaces seem to create a closed
surface loop, it is not possible to create a volume surrounded by them?
Many thanks in advance for your help
