Like a shared edge, a suppressed edge indicates geometric continuity between two surfaces but, unlike a shared edge, the automesher will mesh across a suppressed edge as if were not even there. The automesher does not place seed nodes along the length of a suppressed edge and, consequently, individual elements will span across it. By suppressing undesirable edges you are effectively combining surfaces into larger logical meshable regions. For shared edges, this is the maximum tangential angle between two surfaces at the shared edge. Edges of surfaces exceeding this angle are not suppressed.
Suppressed edge:被压缩的边,被二个面共享,在划分网格时被忽略,不会在上面布置节点。在压缩边上,两个相邻的曲面实际上被缝合成一个较大的曲面,颜色为深蓝色 。某种意义上说相当于删除。breakangle就是一个识别你这两个面多大角度时候可以压缩这条线。
