我的优化过程总是出错优化过程总共分为六个工况,第一和第六工况算在一起优化时不会出错,第2,3,4,5工况放在一起时也不会出错,但只要一到六工况放在一起优化时就出错,不知为什么
优化出错的信息如下
RAM:1313MB total ,1313MB used.
Data arrays: 396 total, 204 allocated.
DATA SET size 182 MB, ram_disk 2MB
****************************
A tatal error has occurred during computations:
***ERROR #312***
In static load case
the compliance is negative or large -6.121367E+17
Optimization /buckling analysis cannot be performed
due to possible rigid body mode
FEASIBLE DESIGN.
RAM: 1313 MB total, 1313MB used
data arrays:396 total, 204 allocated.
……
*****************************

请各位帮我分析一下错误的原因在哪
