Hello,

I'm new to GMSH I want to make a cylindrical electrode shape with 2 contacts.
my problem is when I want to generate 3d mesh it produces the error

"Pyramid top vertex already classified on volume 1 (!= 2) - non-manifold quad boundaries not supported yet"


this is my code.



gridsize = 1.0;

// define Electrode
Point(1) = { 0, 0, 0, gridsize};
Point(2) = { -.2, 0, 0, gridsize};
Point(3) = {-.65, 0, 0, gridsize};
Point(4) = { .65, 0, 0, gridsize};
Point(5) = { 0, .65, 0, gridsize};
Point(6) = { 0,-.65, 0, gridsize};
Ellipse(1) = {5,1,2,3};
Ellipse(2) = {4,1,2,5};
Ellipse(3) = {6,1,2,3};
Ellipse(4) = {4,1,2,6};

Line Loop(7) = {1,-3,-4,2};
Plane Surface(1) = {7};


s0[] = Extrude{0, 0, 1.5} {Surface{1};};
Transfinite Surface {s0}; Recombine Surface {s0};

s1[] = Extrude{0, 0, .5} {Surface{s0};};
Transfinite Surface {s1}; Recombine Surface {s1};
