模态分析 报错

算一个作动器的模态分析（有预应力），存在绑定接触和不分离接触，计算结果一直报错：An internal solution magnitude limit was exceeded. Please check your environment for inappropriate load values or insufficient supports. Also check that your mesh has more than 1 element in at least 2 directions if solid brick elements are present. Please see the troubleshooting section of the help system for more information.调整了网格密度什么的也没有用，不知道该从哪方面修改模型呢？本人workbench刚使用没有多久，实属小白一枚，求各位大侠不吝赐教，小女子感激不尽！
