Mixing structured with unstructed mesh
 

Hello everybody

I trying to mesh a surface boat with the bottom structured and the rest unstructured.
Check this post:

I want to do the same mesh than the picture but with the boat, mixing structured with unstructured. I use in volume mesh the octree method and existing mesh part (for including the structured mesh)
I put the tin and the blk in dropbox.

I am not capable to mesh it ! I do it for the appendices (picture) but for the boat , this is not working, perhaps about the topology or faceted surfaces of the boat.

If you have a solution or advice.
Thank you in advance
