Prism layers on duct
 

Hello guys.

I'm struggling with generating mesh around propeller's duct. I managed to generate structured mesh in the domain, but I can't generate prism layers(inflation). I did this mesh in Workbench and I thought that I could export my mesh to ICEM and then generate some prism layers, but when I simply try to generate it by Compute Mesh -> Prism Mesh, for selected parts it doesn't work. Is there any simple way to generate prism layers on my geometry?

I will appreciate it if anybody will help me with this issue.

if you want prism layer with structured mesh in ICEM, you need to block your geometry !

Thanks for the reply.
I need to learn blocking in the near future.
