My transient simulation showed sudden divergence from iteration number 247880. Residuals reached to the scale of 1e+141 in next 500 iterations. I identified the problem and I want to fix it. Is there a way to delete/undo the solution of those last 500 iterations and apply the fix so that I can avoid re-running the solution from iteration 1 which would take almost 60hrs of computation time.
Thank you in advance,

It's not possible to go back to an arbitrary iteration. Otherwise StarCCM+ would need to save the data of all gridpoints for every iteration. This would create huge files.
If you want to avoid such a problem I recommend the autosave feature. This lets you save your simulation every x-steps (lets say 100 for example) in a new file. That's the easiest solution to avoid such problems in the future.
