Regarding convergence issues, experts, please step in!

I wonder if anyone has encountered the same situation as me: in one simulation, it did not converge; after changing a few parameters, I ran it without reinitializing it, and as a result, it became functional and converged； However, when running it after initialization, the results do not converge; but upon checking the results, it turns out that convergence is not far off. Now the question is: in such a situation, can it be said that this simulation can converge, but it failed to do so merely because the simulation settings were not optimal enough? If you know, please let me know; I’d be extremely grateful!
Reply to 1# wen8694bing: This can’t really be considered a valid convergence. Since you didn’t initialize anything before starting the computation, it’s possible that previous results influenced the calculation process; as a result, the computation seems to succeed, but this is actually just an illusion of success.
