Abaqus 出现“The area of XXX elements is zero, small, or negative”错误提示

Abaqus “提示单元面积为零,很小或者为负数” 错误,如下所示:

The area of 2500 elements is zero, small, or negative. Check coordinates or node numbering, or modify the mesh seed. The elements have been identified in element set ErrElemAreaSmallNegZero.

Analysis Input File Processor exited with an error.

经仔细检查,是因为单元编号顺序出现了错误,将单元编号顺序改为逆时针即可解决问题。

    可以尝试的解决方法:如果是三维网格,并且有tie constraint的话,可能是你勾选了tie constraint对话框里的:adjust slave surface initial position。 要是勾选的话,系统会调整节点位置,导致相关网格质量不合格。 亲测有效。如果是二维网格,有可能是跟法线方向(也就是单元的节点编号)有关。这个我没试过。
