ok what you can do:
for each sharp angle (like the picture):
*create a vertex at location on one of the edges which generates sharp angle
*do the same for the other edges

Ok I checked you model, and the volumes are connected, so it is ok from this side.
Now since you have meshed it, have you checked the max skew cells? (examine mesh icon and check how many cells...

are you sure that your 2 volumes are connected?
*click on the connectivity icon next to examine mesh, and check if the interfaces between your 2 volumes appear in pink

yes the 2 volumes have to be connected, else gambit creates walls at the interface between the 2 volumes.
Go to Surface / Connect, and choose real-virtuals (the last one), and All entities.

What kinds of error?
Do you get also error, if you try to mesh the brick without BL?
(was the hull not already substracted from the big brick?)
I give you a tip: merge surfaces, once you made...

try to reduce the max skewness below 0.9
With high skewed cells, you may have convergence problems.
Try to localize the cells with high skewness. I am pretty sure they are on the hull (sharp...

If you want to use enhanced...

:eek: Check tubulence theory, especially log-law for wall treatment.
But maybe you wanted to say, that the flow is laminar
Anyway.
Regarding the mesh, you have to split the domain with your brick....

I would create a brick or ellipsoid around the hull for controlling the mesh growth (and also preventing for memory issue)
Then on this new volume (with the hull), create a Size Function on hull...
