Hello Everyone!

For my Master's thesis, I am currently trying to mesh a complete aircraft (Dornier 228) with its two propellers. I already have the CAD file, adapted for ICEM CFD (proper model, with curves, points,...).

The final goal of my thesis is to study the boundary layer at a specific location on the side of the aircraft. For this reason, I would like to build a structured, or at least hybrid mesh to properly capture this boundary layer.

My problem is: I don't have a lot of experience in CFD, and even if I have done all the ICEM tutorials, none of them deals with such a complex configuration. I have tried to create a blocking structure on my case, but it is causing me some troubles!

If you could recommend me a tutorial (I haven't found any), a book on the subject, or any advice, it would be extremely nice from you!

I can always do a fully unstructured mesh, with a prism layer at the wall and some density regions, but I would really like to know how to create a structured mesh!

Thank you very much for your help!

Joachim

If you plan to model the propellers, you should probably put the discs in early so you account for them in your blocking...

I would be interested to see the final blocking for this case
