Hi,
well, did i miss any answers? so far i'm still stuck on this problem.
maybe i send the request at a bad date ...
Hi Bernhard,
yes, it must be the date, sorry for the delay.
The short answer is that the extrusion along normals does only work in 3D (extrusion of a surface to create a volume)
and has not been implemented in 2D. (We needed only the 3D , lack of time, it's not that simple in 2D because we don't
have the normals, ...).
In 2D, I suggest you to use Transfinite Surfaces.

Hello all,
well, here is again the old problem, but somehow i don't get it. I'm
trying to somehow create a quadrilateral layer on the surface in the
attached file. It is not ideal yet, but at least to get to that layer
would be nice.
I tried the method described in
http://www.cfd-online.com/Forums/openfoam-meshing-gmsh/61876-default-faces-boundary-layer.html
(as mentioned in http://www.geuz.org/pipermail/gmsh/2009/004551.html) in
the file. But somehow i just get a 3D extrusion instead of a 2D extrusion
normal to the surfaces.
The compound line and surface method from
http://www.geuz.org/pipermail/gmsh/2009/005068.html crashes with my gmsh
version (2.3.1).
Now what? Is it somehow possible to create a quadrilateral layer on the
surface?
