Writing different time steps in different processors

Hi
I have a problem. Sometimes when my simulation stops, it stops at different time steps. When I delete the latest time step which is different and make all time steps same and restart the simulations, the simulations run but do not write the data at all. For this reason, I have deleted my simulations several times and start them new. This is a source of constant time waste. Right now I have again stopped at this situation and in order to save my three weeks of run-time, I am trying to figure out how I can restart it without deleting anything. For this , I have used the startTime in controlDict as last time step which is the last common time step in all processors which was 0.484834. It failed and the error was error1 attached. I went into the processors/0.484834/uniform/time and saw the time there which was 0.484834. In fieldAveragingProperties, iteration was saying 0.484835. I used this. It again failed. Error 2 attached. I shall be grateful for help. Regards Imad |

Hi Imad,
We've been going through this for quite sometime now and many times you keep forgetting to state which exact version of OpenFOAM you're using. Quoting from the post that got me here: Quote:
A few days before this post above, you posted this bug report: http://www.openfoam.org/mantisbt/view.php?id=1355#c3178 __________________ Now, going to this recent problem that you have in this particular thread, the problem indicated by both error messages is that you have defined a double value where a word should be. This is because you have defined this: Code:
startFrom 0.484834; Code:
startFrom 0.484835; Code:
startFrom startTime; startTime 0.484834; When in doubt, double-check the User Guide: http://www.openfoam.org/docs/user/controlDict.php - and look at the files in the "tutorials" folder. Best regards, Bruno
