Hello,
I tried a restart and It may worked but one thing it is not clear: my residual.csv shows the same number of iteration as the first calculation; although the file was written at the end of the restart calcultion.
I did two steady simulation:
1) 10 iteration
2-restart) 15 iterations

FA

Hello,
It's strange... you should have the number of iterations of each run, like in the following example.
You can force the flush of the listing, residuals ant time_stat using the control_file, check the user guide there is info about the use of the control_file.

Luciano

Hi Luciano,
thanks you for your answer!
I was thinking I might have made a mistake launching the restart: maybe I should have launched it from the checkpoint directory!? I will try doing that and looking at the use of the control file.

Hi Luciano,
I read about the use of the control file in the user guide. All the main options are listed but I do not have a clear idea of what suits my issue. What does the flush option do?

Hi everybody,
problem solved! I was launching the job from the wrong directory.
The restart was not pointing at the checkpoint directory of the previous calculation.

Hi everybody,
still a question regarding a restart from a job (RESU/YYYYMMdd-hhmm) which was restarted; please forgive the play of words: in practical terms in the folder I am considering (YYYYMMdd-hhmm) there are both a checkpoint and a restart directories.
If I want to do a new restart from this job; do I have to point the new job to the restart directory or the checkpoint directory?
Both checkpoint and restart directories contain the files for a restart (main and auxiliary).
Hope I have been clear enough...
Best regards,
FA

Regarding my post I think the answer is the checkpoint directory because the restart is created in YYYYMMdd-hhmm when a job "is called" from the checkpoint directory.

Hello,
A computation reads a restart (if present) and generates a checkpoint.
The restart in an execution directory is usually a symbolic link to a checkpoint from a previous run (except maybe on Windows where it might be a copy).
So you probably want the checkpoint.
