abaqus(求助帖)The volume of 13 elements is zero
The volume of 13 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.按照书本上的错误分析做了，还是没用，有人跟我说是单元体划分质量不好，让我更改单元体的大小，可以减少数目，但还是不能完全去除，而且无规律可循，网格划分大了影响分析结果。不知道有什么实用的方法吗？
