Setup shut down while run calculation

      Hi Everyone,


      I was running my calculation for 12 hours. Suddenly, the setup window closed.


      May I know what is the possible cause for this issue?


      I reopen the setup , however it doesn't say anything on the console.


      it halts again and showing this message

      Have a look in the Workbench folder to see if there's a .trn fluid in the /FLU folder. That may have something useful in it.

      Hi rwoolhou,


      Unfortunately, I couldn't find anything there. It seems it never compute from the start.

      Does anyone knows how big the file per iteration? It took so much hard drive space.

      If you're saving data every iteration it'll write a case & data file each time: the size will depend on the cell count (mesh) and number of models active.

      Thank you very much rwoolhou,


      I will try method suggested in link below.
