Stephan,
I just looked them up in the graphical window. You can always check the
indices of the geometrical entities using
Options->Geometry->Visibility->... (see the attached figure).
Best,
Mikhail

Dear Mikhail,
great, your solution works. Thanks a lot.
The reason why it did not work for me, is that I did not (and in fact
still don't) know how extrude determines the id's of the outer
surfaces. I tried to look it up in the manual:
http://www.manpagez.com/info/gmsh/gmsh-2.2.6/gmsh_36.php
But it does not seem to be described there.
How did you know that the relevant numbers were: 13, 25, 37, 49, 10,
22, 34, 46 ?
Thanks again,
Stephan

Hi Stephan,
I selected the outer surfaces as "Physical Surfaces", and it seems to
work for me. Please, add this line at the end of your file and see if
it works for you as well (as you know, you can replace 101 with
whatever number you want to describe the outer surfaces).
Physical Surface(101) = { 13, 25, 37, 49, 10, 22, 34, 46 };
Best,
Mikhail

Dear all,
I have created a script which meshes an axisymmetric surface by
extrusion (see attachment). Then the mesh contains both the outer
surface of revolution as well as the four inner auxiliary surfaces
which
were used/created by the extrusion.
In the final mesh, I would like to have only the outer surface of
revolution. I have tried to either delete the inner surfaces or to
select only the outer surfaces as "Physical Surfaces". Both attempts
have failed.
Would someone have a hint how to go about that?
Thanks a lot in advance!
Stephan
