ansys瞬态动力学分析出现如下问题：
The solver engine was unable to converge on a solution for the nonlinear problem as constrained. Please see the Troubleshoot ing section of th e Help S ystem for more information.
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.
One or more contact regions may not be in initial contact. Check results carefully. Refer to Troubleshooting in the Help System for more details.
Contact status has experienced an abrupt change. Check results carefully for possible contact separation.
请各位帮忙指点下，不胜感激。
