Three factorizations in a row failed. Check the model. It is possible that the model contains the kinematic coupling definition set up in a way that a degree of freedom has neither mass nor stiffness。

溫度位移耦合和振動(dòng)分析單獨(dú)分開(kāi)來(lái)是沒(méi)問(wèn)題的，但是把他們銜接上就會(huì)出現(xiàn)問(wèn)題，每次在完成溫度位移耦合分析后就直接報(bào)錯(cuò)了，進(jìn)行不了振動(dòng)分析，顯示Three factorizations in a row failed. Check the model. It is possible that the model contains the kinematic coupling definition set up in a way that a degree of freedom has neither mass nor stiffness？
