Hello,

I am running a simulation with very small time steps over a long period of time. Sometimes in the middle it crashes and I have to restart it. I am saving the case and data using autosave at regular intervals. However, I am monitoring the volume average of temperature using a report definition and also write it in a file. When I restart my simulation the data in the reportplot and file both start from the current iteration, losing all time-steps from before. Is there a file or way in which I can get all the history of the data in the report defination and not just of the recent simulations.

Thanks
Abdur

There is no super smart automated way.

If you are using a report, there should be a prompt at some point to overwrite or no. If you choose no, then it does not delete the files and will retain the old history. The problem is, it will append the new data to the end so that you will have a section of redundant data (i.e. between your autosave and when it crashed). You have to parse through this and delete the redundant data.

Alternatively, you can backup the old reports by renaming them or something, and then parse the files.

Thank you for the reply.


Can you tell me where is the whole history ? In the data file ? Can I also somehow extract the data to use in excel later on ?

I couldnt find any option in the report definations section ?

I read the FLUENT manual but couldnt find any information about the basics of data saving and manipulating ? Any guide or help would be highly appreciated.

The history is in the report file that you write which I presume you know how to find based on:

The report is a space delimited file and can easily be imported into excel using the excel import tools.

The overwrite prompt occurs when you hit the calculate button.
