[highhopes]

Hello Everyone,

I've been trying to generate block-structured mesh in a geometry as you can see in the picture. However I couldn't get any decent cells with acceptable quality. I have tried axial cross sections for edge association and now I'm trying the helical cross section, however I am not expecting any luck because every single mesh row seems to follow the helical paths all the way between the two outlets of the helical-guttered cylinder below.

I would appreciate any kind of help, Thanks in advance.
