workbench 瞬态动力学分析行星传动出错

1、One or more contact regions has been defined as nonlinear contact. However, an eigenvalue or harmonic analysis has been performed which uses the initial contact status in that solution. Check results carefully.
2、Contact status has experienced an abrupt change. Check results carefully for possible contact separation.
3、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.（以上是警告）
4、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.（此条为错误）

望各位大神给予帮助！
