here I use a fairly small mesh size in the fluid domain and have tried using quite a lot of inflation layers with y+ = 1, but the results are still not right. however, for the mesh in the solid domain, I still have quite rough settings, and not as small as in the fluid domain.

ah for the record, in my reference journal they use y+ = 5, with a maximum element mesh of 5 million. I've matched them as closely as possible to my references, though I don't know how small their smallest mesh is in the solid domain.
