Need help in meshing volume with Cooper mesh scheme in GAMBIT
 

Dear Friends,
i m modelling a journal bearing with one groove in gambit.
I have created a volume and want to mesh this volume by using "Hex/Wedge" and cooper scheme. My pressure inlet is bearing (outer surface) and output is shaft (inner surface) . Kindly help me in how to mesh this and choose inlet and outlet as source. Also help me in specifying pressure inlet and outlet while specifying boundary conditions in zone type.Kindly help.Thanks in advance.
The volume created and error i have got is attached.
