ansys workbench如何查看警告里出现的弱弹簧反力?如题,分析之后出现警告信息：One or more bodies may be underconstrained and experiencing rigid body motion.Weak springs have been added to attain a solution.Refer to Troubleshooting in the Help System for more details.有种说法是只要在environment下的弱弹簧反力小于e-5,就可以视作正常.可是该怎么查看弱弹簧反力?另外警告信息：An iterative solver was used for this model.However,a direct solver may enhance performance.Consider specifying the use of a direct solver.Refer to Troubleshooting in the Help System for more details.要怎么处理,是不是不管就可以了? 英语

【答案】 对于弱弹簧的反力可以通过在结果中插入probe来观察
迭代解法不影响结果,但会增加求解时间,此时如果强制直接求解可能会使求解失败.
