ANSYS 网格划分 [复制链接]

我在建模过程中，进行网格划分时总会出现（16 angles less than 2.5 degrees found in triangle facets of volume 1, with smallest angle is 1.5, poor element quality of mesh failure may result.），本人诚挚邀请各位大神指点

poor element quality，说明网格划分质量较差，试试将网格尺寸减小，划分密些。

Boundarysegment touch or are too close for meshing.Redefine number of division on boundary or adjust element size parameters  请问这种情况怎么解决呢？网上有人说要在modeling里面用布尔运算优化模型  如何优化呢？拜请大神指导
