[Gmsh] 3D mesh

[Philippe Ackerer]

Hi
I missunderstood something. I plan to discretize a colmun.
Could you explain me why only plan z=0 (nodes and elements) is stored in 
the .msh file ?
I want also to identify the top surfaces, as I have done for the bottom 
surfaces (physical surface 101 and 'Dirichlet'). Any tips are welcome.
I attached the file.
Thanks and thanks a lot for this very helpfull mesh generator.

Best regards
Philippe

// As usual, we start by defining some variables:

r1=0.01;
r2=0.10;
Lcw=0.001;
Lc1 =0.005;
teta=3.14159/3.0;

// Then we define some points and some lines using these variables:

Point(1) = { 0.0, 0.0  , 0.0 , Lcw};
Point(2) = { r1, 0.0   , 0.0 , Lcw};
Point(3) = { r2 , 0.0   , 0.0 , Lc1};
x1=r1*Cos(teta);
y1=r1*Sin(teta);
Point(4) = { x1 , y1 , 0.0 , Lcw};
x1=r2*Cos(teta);
y1=r2*Sin(teta);
Point(5) = { x1 , y1 , 0.0 , Lc1};
