Hi,
I want to mesh a cylinder (see attached file) and need the identity
numbers of the bottom, top and sides (will be used to define boundary
conditions).
Can you explain the numbering that appears in out[] (see attached file) ??
Thanks
Best regards and congratulations for Gmsh,
Philippe

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

Point(3) = { x1 , y1 , 0.0 , Lc1};
Circle(1) = {2,1,3};
Line(10) = {1,2};
Line(11) = {3,1};
Line Loop(21) = {10,1,11}; Plane Surface(22) = {21};

Printf(" Top=%g", out[0]);
Printf(" Lateral=%g", out[1]);
Printf(" Lateral=%g", out[2]);
Printf(" Lateral=%g", out[3]);
