我想创建一个空心或厚半托,为此,我使用以下命令:
setfactory ("OpenCASCADE");
Torus (1) = {0,170,30,Pi};
Torus (2) = {0,20,Pi};
BooleanDifference (8) = {Volume {1}; Delete; } {Volume {2}; Delete; };
当我尝试创建3D网格时,出现以下错误:
PLC Error: A segment and a facet intersect at point Info: (122,229,106,391,-9.48334). Info: Segment: [314,311] # -1 (0) Info: Facet: [7,54,60] # 1 Error: Invalid boundary mesh (segment-facet intersection) on surface 1,intersection (122.229,106.391,-9.48334) Error: No elements in volume 8
为什么会这样?怎么解决?。
