rafmal808 is on a distinguished road
I am having an issue where all transient simulation progress (*.dat.gz, *.cas.gz) is deleted upon crashing (during calculating). The crashing itself isn't an issue, because I used to be able to open the most recent solution file and resume the simulation from that point. However, the program is now deleting all simulation results in the FFF/Fluent folder when crashing. The only error in the log is "Error [Node 0] Abnormal Exit!".


When the simulation runs, I monitor the FFF/Fluent folder and notice there are thousands of case and data files (I have autosave set to every 10 timesteps) but after the program crashes they are all gone. Is there any solution to this? Also I apologize in advance if this software behavior is expected, since I am just a student with only a few weeks experience with CFD.
