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。

温度位移耦合和振动分析单独分开来是没问题的，但是把他们衔接上就会出现问题，每次在完成温度位移耦合分析后就直接报错了，进行不了振动分析，显示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？
