[Gmsh] Meshing a plate with one layer of elements along the thickness

[Phu Nguyen]

Dear all,

I have a simple rectangular plate, which is made by extruding one surface along the thickness

Extrude {0,0,t} {
  Surface{201,202,203}; Layers{1}; Recombine;
}

Then, I used mesh with all hexas in Subdivision algorithm, I got hexahedral elements, as I need, but there are always two layers of elements along the thickness. 

My question is how to have only 1 single layer of elements along the thickness? Many thanks.

Best regards,
Phu
