[Gmsh] 3D Mesh not generated

[Zenker, Dr. Matthias]

Hi,

I can generate and view the mesh without problems.
Is "Volume Edges" or "Volume Faces" checked under Tools->Options->Mesh->General?  Then you should see your mesh.

HTH,

Matthias

Betreff: [Gmsh] 3D Mesh not generated

Hi,

I am trying to generate a simple 3D mesh of a plate of size 50 X 50 X 0.01.  I started with the 2D code of the same plate
and it works well.
When I tried to extend it to 3D using extrude command, I am unable to see the mesh eventhough my terminal says that
3D mesh has been generated.  Could you please tell me whether my code has any mistake?  Below is the code for your
reference.

Point(1) = {25, 25, 0, 1.0};
Point(2) = {-4, 25, 0, 1.0};
Point(3) = {-6, 25, 0, 1.0};
Point(4) = {-14, 25, 0, 1.0};
Point(5) = {-16, 25, 0, 1.0};
Point(6) = {-25, 25, 0, 1.0};
Point(7) = {-25, -25, 0, 1.0};
Point(8) = {-16, -25, 0, 1.0};
Point(9) = {-14, -25, 0, 1.0};
Point(10) = {-6, -25, 0, 1.0};
Point(11) = {-4, -25, 0, 1.0};
Point(12) = {25, -25, 0, 1.0};

Line(1) = {1, 2};
Line(2) = {2, 3};
Line(3) = {3, 4};
Line(4) = {4, 5};
Line(5) = {5, 6};
Line(6) = {6, 7};
Line(7) = {7, 8};
Line(8) = {8, 9};
Line(9) = {9, 10};
Line(10) = {10, 11};
Line(11) = {11, 12};
Line(12) = {12, 1};

Line Loop(5) = {1,2,3,4,5,6,7,8,9,10,11,12};
Plane Surface(60) = {5};
Physical Line(100)={1,3,5,6,7,9,11,12};
Physical Line('elec1')={2};
Physical Line('elec2')={4};
Physical Line('elec3')={8};
Physical Line('elec4')={10};

Physical Surface(200)={60};

Transfinite Line(1)=29;
Transfinite Line(2)=3;
Transfinite Line(3)=8;
Transfinite Line(4)=3;
Transfinite Line(5)=9;
Transfinite Line(6)=50;
Transfinite Line(7)=9;
Transfinite Line(8)=3;
Transfinite Line(9)=8;
Transfinite Line(10)=3;
Transfinite Line(11)=29;
Transfinite Line(12)=50;

Transfinite Surface(60)={1,6,7,12};
Recombine Surface(60);

Extrude {0,0,1.01} {Surface{60}; Layers{2}; Recombine; }

Thanks.

Best regards
Lakshmi.
