Hello,

I am using Ansys Explicit Dynamics 2024-R2. I have set End time=1s in settings and also the maximum number of cycles are big enough to capture whole simulation. The problem is that my simulation finish before 1s and the last cycle is also much less than maximum number of cycles in analysis settings. I would be appreciated if you can tell me what can i do to finish my analysis till the end time reaches. Please let me know if you need more info about my project. 

Thank you!

Energy Summary plot shows that there is a negative contact energy developed with time. Negative contact energy means large contact penetrations present in the results. 

Thus, please check your results carefully. The premature interruptions may be caused by large contact penetrations.

Furthermore, you can restart the analysis by selecting the last saved cycle via Resume From Cycle in Step Controls under Analysis Settings and then click on Solve. Program should continue the analysis from the last restart file saved. It may not be the last cycle when it was interrupted: 244510.

Also, the time step is 7E-7 ms, which is quite large in a typical explicit dynamics simulation. Please check the material properties carefully to make sure they are accurate.
