我也有同样的问题，期待中。。。。。。。

这个问题涉及到了有限元理论，以及mechanica的理论基础。
好像mechanica只能做线性分析，而非线性就做不了了。
更详细的情况见帮助，写的非常详细，你可以好好看看，就会发现很多问题迎刃而解的。
下面文字引自帮助。

Singularities
Mechanica Structure is based on the theory of linear elasticity, which is a useful approximation of physical reality. Linear elasticity allows solutions that have infinite values of displacement or stress. These solutions with infinite values are called singular elastic states and the locations where they occur are called singularities.

At the location of a singularity and in the small area around the singularity, the theoretical elasticity solution is not a valid representation of physical reality because displacement and stress cannot be infinite. Outside the area of the singularity, the theoretical elasticity solution is valid. Structure attempts to represent the singular representation as accurately as possible using polynomial functions.

Singularities cause edges in a model to require a high p-level for convergence, thus resulting in a longer solution time. Some of the most common locations where element singularities can occur include:

at reentrant corners

at point loads and constraints

along line loads and constraints on solids

at the interface between elements of different properties, materials, or element types

To understand the causes of singularities, see Singularities and Loads or Singularities and Constraints.

mechanica可以做非线性分析，但是强烈建议你不要去掉星号，它标出来意思是表明哪些地方的数据有可能是结构的奇异点，需要用其它工程技术手段判断的，要去掉不是有点“混淆十分”！
