Hi everyone,
I'm meshing a motorboat with a relative compelx geometry.

I've been working on this quiet hardly to get nice and continuous boundary layer along the hull. However, I'm not growing boundary layer mesh at some specific patch to save cells.

I just came accross a very weird defect. If I visualize the hull, I can see some kind of flaps made of the face of the boundary layer, at the junction of a patch where there is no BL mesh.
I think a picture is better than words so please see attached pictures.

My worry is that those face are suppose to be internal cell (so inside the fluid), I'm worried that there may be no flux through those face.

Any idea where it can come from?

Thx for your help
