Hi,

your .geo file is not correct : 

a) the lines 

Recombine Surface {200} ;
Recombine Surface {201} ;
Recombine Surface {202} ;

directly after the creation of the Plane Surfaces are useless and should be cancelled.

b) the big problem is that when you Extrude Surface 200 ( Extrude Surface { 200, {0, 0, 0.016} } ; ), one of the lateral faces which are created , Plane Surface 219 , is partly superposed to the already existing surface 202 . Also, the line 205 which is created by the extrusion intersects lines 29 and 35, and no Point exists at these intersections. In these conditions, it is normal that gmsh hangs.

When you look at the 2D mesh of your file, you can already see that they are some problems and that the mesh is not good in some regions.
