3D螺旋线圈周围空气区域网格剖分
本帖最后由 funnylinc 于 2013-2-22 15:43 编辑3D螺旋线圈被包围在立方体空气区域中，单元类型均为solid122，对空气区域网格划分总是失败，望指教，谢谢！下附命令流：

加上最后一句vmesh,3，自由剖分运行半小时都没完，改用手动剖分，设置LESIZE运行结束显示错误：
vmesh failure，perhaps due to：
（1）poorly shaped triangular facets：mesh area with triangular elements，modify mesh control or turn on smartsizing to get good triangular mesh，then vmesh again。
（2）complex geometry：subdivide volume&try again
