Hi Dharmendar, What you get is the normal behaviour. As the Coherence is done at the level of the geometry, lines 5 and 9 coincide with line 13, but they are not the same. That's why you get double mesh points.
You should not extrude line 3 in that way. See the work around I would use in the attached file.

Can some one help me with this. I am creating an extruded mesh using gmsh. I happen to see duplicate nodes in the msh file. How do i get around this ?
thanks
Reddy
The following is the .geo file
// Test geo
t1 = 2;
t2 = 1;
L1 = 5;
L2 = 10;
L3 = 5;
//contol length of mesh
Lc = 1;
N1=5;
N2=10;
N3=5;
Point(1) = {0, 0, 0, Lc};
Point(2) = {0, -t1, 0, Lc};
Line(1) ={1,2};
Point(4) = {0,t2,0,Lc};
Line(3)={1,4};
out1[] = Extrude {L1+L2,0,0}{
Line{1}; Layers{N1+N2}; Recombine;
};
out2[] = Extrude {L3,0,0}{
Line{out1[0]}; Layers{N3}; Recombine;
};
out4[] = Extrude {L1+L2+L3,0,0}{
Line{3}; Layers{N1+N2+N3}; Recombine;
};
