Hello there!

I am generating a structured mesh for a duct in ANSYS ICEM using the Multizone meshing method. I have executed the following:
a. Global and Part mesh parameters setup. Connectivity was alright between surface patches;
b. Automatic surface blocking;
c. Creation of Ogrid around faces
There is however difficulty in generating the 3D mesh from the surface mesh: I see a missing part of the duct when I create the 3D mesh (as shown below).
I am working at generating the 3D mesh and improving the quality manually positioning vertices or modifying the edge parameters, but now stuck as part of the geometry disappears when I attempt to extrude the surface mesh. I have been following steps highlighted in ICEM CFD Tutorials (Multizone Mesh in HVAC Square-to-circle Transition Duct).

I am indeed grateful for any guidance on how to resolve this issue or better still, an alternative approach to generate the needed structured mesh for this duct.

Thanks a ton!
Ayo
