I am trying to mesh a badminton shuttlecock within a fluid. That means, I have it like how the "blunt body tutorial" is teaching- a shuttlecock "boxed" by a liquid body.

My problem is that with tetra only, the mesh quality is relatively acceptable. When prism layer is added, the quality goes all the way down. This is despite a reduced maximum size of the prism layer.

I have attached photos.

The problem I have is that the feather of the shuttlecock overlaps each other. In between the overlap of two feathers is a small tight sharp corner. At that area, the mesh elements are of very poor quality, even at decreased size.

I can't quite decrease the size too much because too many elements will cause my computer to run out of memory when loading the prism.uns thingy. Yet, my computer is a 2600k with 16gb of ram...so I really think the problem is ME, not hardware limitation. I mean this is just a shuttlecock, can't be that complicated right?

1. What should I do to improve the mesh quality?

2. Since shuttle is within a fluid, I should set the shuttlecock surface as split wall?
