[Gmsh] error 3 identical points in Qtest

[Timothy Phung]

Hi,

I have been trying to create a mesh out of this geo file in gmsh but it gives me an error that there are 3 identical points in Qtest. I am quite new to gmsh. Can someone please point me to where this error may be in my file, which is shown below.

Point(1) = {500, -125, 1, 0.1};
Point(2) = {500, -125, -1, 0.1};
Point(3) = {-500, -125, -1, 0.1};
Point(4) = {-500, -125, 1, 0.1};
Point(5) = {500, 125, 1, 0.1};
Point(6) = {500, 125, -1, 0.1};
Point(7) = {-500, 125, -1, 0.1};
Point(8) = {-500, 125, 1, 0.1};
Line (1) = {1, 2};
Line (2) = {2, 3};
Line (3) = {3, 4};
Line (4) = {4, 1};
Line (5) = {1, 5};
Line (6) = {2, 6};
Line (7) = {3, 7};
Line (8) = {4, 8};
Line (9) = {5, 6};
Line (10) = {6, 7};
Line (11) = {7, 8};
Line (12) = {8, 5};
Line Loop (1000014) = {6, 10, -7, -2};
Plane Surface (14) = {1000014};
Line Loop (1000016) = {4, 1, 2, 3};
Plane Surface (16) = {1000016};
Line Loop (1000018) = {12, 9, 10, 11};
Plane Surface (18) = {1000018};
Line Loop (1000020) = {6, -9, -5, 1};
Plane Surface (20) = {1000020};
Line Loop (1000022) = {7, 11, -8, -3};
Plane Surface (22) = {1000022};
Line Loop (1000024) = {4, 5, -12, -8};
Plane Surface (24) = {1000024};
Surface Loop (1000026) = {14, 20, 18, 24, 16, 22};
Volume (26) = {1000026};
