My goal is to create an air-solid model for a turbomachinery blade passage to be used for unstrcutured meshing in NX.
I have 6 surfaces now (inlet/outlet, hub/casing, periodic up/down). I sew them together to form an air-solid body by Menu --> Insert --> Combine --> Sew, Type = Sheet, Tolerance = 0.0004 (Default) (Fig.1)
The next step would be to trim this air-solid body by a 3D blade surface that extends beyond the hub and casing faces to add an internal blade surface. I do this by Menu --> Insert --> Trim --> Trim Body (Fig. 2) The problem can already be seen in Fig.2:The sewn body is NOT air solid as I expected. It is merely 6 surfaces joined together.Therefore when I trim this sewn "body", only the hub and casing surfaces are to be trimmed (you could see that only the hub and casing airfoil profiles are highlighted in Fig. 2, otherwise the whole 3D blade should be highlighted). Fig. 3 is after I click on "Reverse Direction" to complete the trim.
What did I do wrong? How can I address this issue? How to make sure the Sew process generates an air-solid body? Any idea would be appreciated. Thank you very much!
