Merge blockMesh and Gambit, failing at zones
 

Dear Foamers,
I'm trying to merge two meshes, where one of them is created in Gambit. It finds the right directories and cases - however, it fails when it comes to "zones" ... returning

cell zone names:
1
(
fluid
)

Copying old patches
Adding new patches.


Illegal zoneID 0 for face 131072#0

Any suggestion on how to improve this? Is it because the blockMesh-mesh does not create zones?
