[Gmsh] Gmsh 2D Boundary Layer around a bluff body

[Tommaso Pascon]

 Good morning,
 

 
I'm Tommaso Pascon a Openfoam CFD user who use Gmsh as a mesh generator software.
 

 
 I'm having troubles trying to get an hybrid mesh with a structured boundary layer area around a bluff body and an unstructured region for the rest of my domain.
 
 I tried with boudarylayer field but i can't make it to work apparently so i decided to use the extrusion function. This is working but i can't connect the structured region with the unstructured one. It seems that these two aren't connected together and the unstructured mesh falls into the structured part.
 
 What am I missing? I've read a lot of posts on that matter but I still can't find a solution.
 If it's needed I can upload the geo file
 
 Thanks
