Read Data File error

      Hello everybody,
       
      I am simulating a 3d, dp, eulerian phase + particle, transient case using fluent 21.2.
      The simulation is working and I am running several timesteps, writing a .dat file of the results of the last timestep, trying to read the same file and fluent gives me the following error:
       
       
      I am thankful for any suggenstions and help

      Did you write case and data at the end of the run? Are any of the intermediate saves OK?

        Overall, the case is supposed to run as a job array and I had cases were I couldn't open the Autosave files as well.

        I am Sorry, I am only writing data at the end of my simulation. I saved the case before start

      Has the mesh or any boundary type changed? The data read suggests the particles are being passed to cells, which I wouldn't expect so I wonder if something's got scrambled between case & data. It's usually good practice to save case & data for results in case something gets changed.

        No nothing has changed. In fact, I wrote the data file and immediately tried to read it again without closing the case or changing anything and fluent was not able to read it.

        And I also tried to save the data first and writing the case file afterwards. 

        I tried to run this in batch mode (thats where the problem originally ocurred) and this gave me some error log file. Maybe there is some information that could help you and I don't understand.

        Thanks for your help!

      Are you writing .cas.gz and .dat.gz or .cas.h5 and .dat.h5 ?  The log's not much use in this case, other than the error may be node related.

        I am writing .dat.h5 and .cas.h5.

        I am running the simulation on a hpc-computer. I just figured out,when using a login node it is surprisingly always node 7 that gives the error (using 30 threads). But in batch mode, I am running on 48 cores with 40 threads and it is always node 10. Is there anything i could do about it?

      Try writing legacy (cas.gz & dat.gz), it's possible there's a data packet loss from one of the nodes. Not sure about the cores as Fluent will use what it's told to (but can't not use a specific thread on a core). Maybe IT need to reboot it?
