[FAQ]

If no error is generated by the auto-save, and there is no evidence from the transcript that Fluent has attempted to write the files, then it is possible that the data-frequency is set to flow-time and not time-step: file auto-save save-data-file-every flow-time In this scenario, a data-frequency of 5 would mean that the next data-file -write is 5 seconds away. The best way to verify this is to open the .cas file in a standalone Fluent session after the journal file has been read and inspect the auto-save settings. Once a .cas file has the flow-time data frequency setting, the journal file will have to first change this setting to time-step and then set the data-frequency: 1. file auto-save save-data-file-every time-step 2. file auto-save data-frequency 5 Doing this in the reverse order may cause the save-data-file-every setting to be ignored or the data-frequency zeroed. (Both will have the effect of the file not getting written.)
