求助划分网格出现错误提示

8316

错误提示：划分网格volume6 cannot be meshed. 2 location(s) found where non-adjacent boudary triangles touch. Geometry configuration may not be valid or smaller element size definition may be required.
   VMESH failure,perhapes due to1) poorly shaped tri facets:mesh areas with tris,.odify mesh control or turn on smartsizing to get good tri mesh, then vmesh again (2) complex geometry: subdivide volume and try again
　　麻烦大家帮我看看哪错　？很着急　，毕业
