优化过程出错 #312
WARINGthe amount of memory allocated for the run is523MB,which
is larger than the specified (or the default)RAM=320MB
this run is intended to use out of core processing in the solver
FEASIBLE DESIGN
a fatal error has occurred during computations
***ERROR# 312***
the compliance is negative or large 7.296452E+12
optimization/ buckling analysis cannot be performed
due to possible rigid body mode

请问这样的错误是什么意思啊,在优化前是能算的,
各个部分应力也是比较合理的,怎么一优化就出现问题呢
请检查约束是否足够。 可以做一个模态分析,看看是否有刚体位移。 我也遇到相同的问题 不明白为什么会柔度过大 同问啊,希望好心人能帮忙解答啊 仔细检查material内的参数看看 问题己解决:解决方法为将memory options设置改成2000或者更大上些,memory default的设置为320,文件过大时容量不够
