我正在尝试制作立方体的四面体网格。我遇到的问题是一些用于生成三角形面的节点然后不用于生成任何四面体元素。有没有办法避免这种情况？这是代码。

    cl__1 = 0.01;
    Point(1) = {0, 0, 0, cl__1};
    Point(2) = {1, 0, 0, cl__1};
    Point(3) = {1, 1, 0, cl__1};
    Point(4) = {0, 1, 0, cl__1};
    Line(1) = {1, 2};
    Line(2) = {2, 3};
    Line(3) = {3, 4};
    Line(4) = {4, 1};
    Line Loop(5) = {4, 1, 2, 3};
    Plane Surface(6) = {5};
    Extrude {0, 0, 1} {
      Surface{6};
    }
    Coherence;
    Transfinite Line {1, 2, 3, 4, 9, 10, 11, 8, 18, 22, 13, 14} = 2 Using Progression 1;
    Transfinite Surface {19};
    Transfinite Surface {23};
    Transfinite Surface {27};
    Transfinite Surface {15};
    Transfinite Surface {28};
    Transfinite Surface {6};
    Transfinite Volume{1} = {1, 2, 3, 4, 6, 10, 14, 5};
    Physical Surface("top") = {28};
    Physical Surface("bottom") = {6};
    Physical Surface("x_min") = {15};
    Physical Surface("x_max") = {23};
    Physical Surface("y_min") = {19};
    Physical Surface("y_max") = {27};
    Physical Volume("bottom_volume") = {1};

谢谢简

该输入的结果给出了这些节点：

$Nodes
8
1 0 0 0
2 1 0 0
3 1 1 0
4 0 1 0
5 0 1 1
6 0 0 1
7 1 0 1
8 1 1 1
$EndNodes

使用这些节点，您可以定义所有三角形面和定义该网格的四面体元素（我认为没有不一致）。
