The volume of 30 elements is zero, small, or negative. Check coordinates or node numbering, or modify the mesh seed. In the case of a tetrahedron this error may indicate that all nodes are located very nearly in a plane. The elements have been identified in element set ErrElemVolSmallNegZero.
Checks on element reactivation have revealed 31 errors. Examine the coordinates/normals listed above, which are based on the displacements/rotations of the nodes of these elements in the last general step
The elements have been identified in element set ErrElemVolSmallNegZero.这句话已经提示你在这个set ErrElemVolSmallNegZero错误集里,所以你要看看这些发生错误的单元在模型的哪些地方,要我分析的话你需要重新画网格 该加密的地方加密 该分割的地方分割
