到constraint,都是用penalty function. 也就是将有constraint的函数设法简化成没有constraint的函数,而不是将每一条的constraint都分开讨论.
4 Z8 X. P" j- T. V* J; ]9 ~
( s$ A( s5 Q! Y0 F1 l' G. O所以本来的函数如果是
" k0 x( h  `% ?+ i& Mto minimize f(x)
# r1 r- T5 Y/ ?- I; vsubjected to g(x) <0
" l; }' ]+ v  I: nANSYS会将之化成
9 `  ~" m. ]. _& C# @2 N# I# }9 P9 d
. V5 ?2 m' e1 H2 G$ ?To minimize f(x)+w*G(x)
2 `" T& w. y8 M  i' ~" U. _
所以,当 (1)函数非线性度高 (2)constraint多 (3)设计变量多 时,收敛就会有问题(optimization解的多半是非线性,而且是不等式,不是等式)

另一个问题就是你提的网格变化的问题了.我可以很肯定地告诉你, 如果循环之间的网格无法保持一致,收敛会容易出现问题. Paramesh有维持网格一致的东功能,但是也不知道跟ansys的整合性如何.为了解决这个问题,有所谓的”natural shape function”方法的出现.在我的网站里

有一篇· S-Y. Chen, Nov 2002, "Integrating ANSYS with Modern Numerical Optimization Techniques - Part II : A Reverse Parametric Modeling Approach for Structural Shaping Optimization, 2002 Taiwan Area ANSYS Users Conference.
可参考一下
6 R1 r) _4 i+ j' h3 G
5 J% C6 `- a* a7 E3 |2 A: N+ M还有ansys多半是取最大应力来作constraint.这也会出问题的. 即使网格可以保持一致的情况下, 只取最大应力都会有问题,何况是网格不能一致?

以下贴两个ANSYS optimization的log file,是很简单的truss结构,但是ANSYS无法收敛.供大家参考…………
