錯誤位置無法找到。是因為模型中定義的接觸非線性？不至于，因為材料非線性？有可能，怎么辦？

* by overflow during elemental matrix computations. *

單元沒有節(jié)點，看看是不是在別的INCLUDE文件中。
遞進式模型調(diào)試的必要性！
隱式分析中遇到的問題，如何應對？
*** 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. *

記得之前也遇到過：
rcmd: socket: Permission denied，不清楚為什么。
如果不去嘗試建立正確的剛度模型，那么動力學模型的精度還能保證嗎？關(guān)鍵的接觸關(guān)系還可靠嗎？
