错误位置无法找到。是因为模型中定义的接触非线性？不至于，因为材料非线性？有可能，怎么办？
正确的输出：

错误：传统梁单元不能用MAT100
错误：关闭AUTOSPC

* AUTOSPC detected very large entries in the *
* assembled matrix. These are probably caused *
* by overflow during elemental matrix computations. *
* This could be caused by an energy explosion. *

单元没有节点，看看是不是在别的INCLUDE文件中。
递进式模型调试的必要性！
隐式分析中遇到的问题，如何应对？
*** Warning 60123 (IMP+123)
**************************************************
* - WARNING - *
* 207 negative eigenvalues detected during *
* factorization of linear equation system. *
* *
* Errors during stiffness matrix inversion are *
* often caused by one of the following problems: *
* *
* 1) Invalid material properties (negative *
* Young's Modulus, zero yield stress...) *
* 2) Inverted element from severe distortion. *
* 3) Rigid Body Modes. Generally, three nodes *
* must be constrained in static analysis. *
* *
* See the User's Manual for more information. *

记得之前也遇到过：
rcmd: socket: Permission denied，不清楚为什么。
如果不去尝试建立正确的刚度模型，那么动力学模型的精度还能保证吗？关键的接触关系还可靠吗？
