inner walls not getting mesh in icem cfd
 

Hi all,

Im trying to mesh a reverse flow annular gas turbine combustor using ICEM CFD.
The name itself reveals that it is annular. When I do surface meshing to it, it is coming proper.
But when I try to make volume mesh for it, the inner geometry i.e. inner walls in the annulus is not getting mesh.
I donno where d problem is...Can someone throw some light on this issue pls...

Regards,
