只贴错误信息谁也没办法吧。你这30个节点是不是在模型表面？

是的，麻烦你帮我看看，我整不出来了，这几天

这是让你看有问题的节点在哪里

这是K文件，麻烦看看

cadence

看了你的文件，好像是单位制的问题。密度很低啊。单位不协调吧。

交大车辆

这个问题出现肯定是模型有问题，检查你的载荷，约束，单位制以及自由单元。

我采用的是mm建模。所以密度应该是吨/mm3，难道不是这样么？求赐教

计算不稳定。。
首先看看出问题的Node在什么位置，你的显示NODE1-30出现问题，看看是不是边界处理、约束等出现问题。
再者建议检查材料模型的单位有没有错，因为模型为mm建模，材料模型里每一个参数都应该检查单位是否正确。或者重新建模。
还有可以关掉K文件里一些关键字，重点在约束、求解、沙漏那，一次关掉一个，一个换一个试。
