Tetrahedra Mesh result
I have a geo file,the contents of the document are as follows:
Point(1) = {0, 0, 0, 1.0};
Point(2) = {1, 0, 0, 1.0};
Point(3) = {1, 0, 1, 1.0};
Point(4) = {0, 0, 1, 1.0};
Line(1) = {1, 4};
Line(2) = {4, 3};
Line(3) = {3, 2};
Line(4) = {2, 1};
Curve Loop(1) = {4, 1, 2, 3};
Plane Surface(1) = {1};
Extrude {0, 5, 0} {
Surface{1}; Layers{5};
}

e {12, 16, 20, 11} = 6 Using Progression 1;
Transfinite Curve {7, 6, 9, 8, 1, 4, 3, 2} = 2 Using Progression 1;
Transfinite Surface {26};
Transfinite Surface {25};
Transfinite Surface {1};
Transfinite Surface {17};
Why only 44 triangles are displayed? This consists of only six triangles on six surfaces of the hexahedron, while the triangles inside the hexahedron are not shown, such as triangles (1,21,4).
