1.Contact status has experienced an abrupt change.  Check results carefully for possible contact separation. 2.One or more MPC contact regions or remote boundary conditions may have conflicts with other applied boundary conditions or other contact or symmetry regions. This may reduce solution accuracy. Tip: You may graphically display FE Connections from the Solution Information Object for non-cyclic analysis. Refer to Troubleshooting in the Help System for more details.
3. The solver engine was unable to converge on a solution for the nonlinear problem as constrained.  Please see the Troubleshooting section of the Help System for more information.
4.The unconverged solution (identified as Substep 999999) is output for analysis debug purposes. Results at this time should not be used for any other purpose.
这是什么原因
新手操作,实在搞不懂,求大神指点。。。

第一个是接触设置有问题或者网格划分有问题,第二个是警告,不用管,第三个是不收敛,要检查的东西比较多,主要是求解的载荷步不够,第4个是载荷步不够
