I have almost finalised the meshing of this nozzle. 
Its fairly structured however for the cone section I get an issue where the mesh isn’t structured anymore, which I think may be due to the Hard edge sizing. It either occurs on the outer faces or the inlet\/outlet faces. I have edge sizing (number of divisions) for the outer face longitudonaly and the outlet\/inlet faces radially. 
When I change different edge sizings to soft, the issue either moves to the inlet\/outlet faces or to the outer longitudonal face of the cone. I have also tried to change the number of divisions for each face, which didn’t work. Is there a way I can get around this?

Another issue I’m having is that the inflation layer doesn’t work. When I tried meshing an inflation layer on the first cylinder I get the following errors.
<\/a>I have seen other people use an inflation layer without problems. However, my geometry is divided into multiple bodies, which might be the reason for failure.
Does anyone know what I can do to stop these errors and get a structured mesh with an inflation layer?<\/p>\n

Thank you in advance!<\/p>\n
