workbench中计算有非线性问题导致的不收敛

静夏之逸

在利用workbench进行瞬态动力学分析时，显示计算有非线性问题导致的不收敛。请问这个错误是什么导致的？怎样解决的。谢谢

错误：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.
警告：The maximum contact stiffness is too big. This may affect the accuracy of the results. You may need to scale the force unit in the model.
警告2：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.
