ANSYS workbench流固耦合时间不一致怎么办？

Update failed for the Solution component in System Coupling.  System coupling run completed with errors.  Transient Structural (Solution 2) reported: The Mechanical beginning time 1 is different from the system coupling service beginning time 0.  This may have been caused by changes made to the Mechanical setup or upstream data. Please do not save the project if you would like to recover to the last saved state.

意思是：瞬态结构（解决方案2）报告：结构开始时间1与系统耦合服务开始时间0不同。这可能是由于机械装置或上游数据的变化引起的。

请问大神这个怎么解决？使用SYSTEM COUPLING进行耦合
