continue iterating from saved case and data file
Recently, I met a very confusing phenomenon. I simulated a reacting flow with Ansys fluent 17.0. I tried to stop iteration and save data files for some reason. Then I reloaded the data file and tried to continue iteration from the point I just quited.
I found the process becomed discontinuous. ie, the results would drop suddenly few iterations after reiteration started and gradully varied slowly then after. I swear I did not change any settings for the case. I just quit, reload and reiterate. I am wondering why would this happen?
