Gambit - Mesh Problem for a complex 3D geometry

Nelson

Hi Everyone,

I am trying to mesh a pretty complex 3D geometry (saying a realistic human airway reconstructed by CT scans) with fine mesh near the wall for internal flow, of course.

I tried "boundary layer" and "size-function" in GAMBIT, however, due to the complex geometry (since it is a non-uniform/rough surface tubes and has lots of flow divider), successful mesh (fine layer of mesh near wall) can never be achieved.

Therefore, is anyone here know how I can mesh this kind of geometry with reasonable computational time and cost in human power to create fine mesh layer near the wall? Thank you so much in advance!
