在做一个零部件静力学分析打开“Large Deflection”出现一下两个警告和一个错误，求行家帮忙解决一下，谢谢。
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.
One or more MPC contact regions or remote boundary conditions may have conflicts with other applied boundary conditions or other contact regions. Tip: You can graphically display FE Connections from the Solution Information Object. Refer to Troubleshooting in the Help System for more details.
An internal solution magnitude limit was exceeded. Please check your Environment for inappropriate load values or insufficient supports. Also check that your mesh has more than 1 element in at least 2 directions if solid brick elements are present. Please see the Troubleshooting section of the Help System for more information.
