Hi,

maybe you want to try an alternative method

Export your nozzle as STL, create an sufficient blockmesh and finally let snappyhexmesh do the meshing for you.

Of course it would be wise, to have an inlet- and outlet- STL.

take a look at motorbike example for snappyhex mesh.
maybe discretizer http://www.discretizer.org/ can help you making the meshing easier.
