problem with restarting the jobs
Hi,
I run some cases with interFoam. But when the running time is up, if I want to continue running the cases, it shows the problem " Build : 1.7.103e7e056c215 Exec : interFoam parallel case .

Thanks. 
Greetings huxiaoxia,
This is pretty simple  the error message reads: Quote:
The time resolution is very small, so if you want to save these small time steps, you'll need to increase the number of digits saved in the folder name! Best regards, Bruno 
Thanks a lot.

Hi huxiaoxia,
you should consider this "warning" only if you think you could have numerical problems due to small time steps. In any other case OF takes care of this, as you can see in the message Time = 0.004280001 > FOAM Warning : From function Time:perator++() in file db/Time/Time.C at line 681 Increased the timePrecision from 7 to 8 to distinguish between timeNames at time 0.00428 It will still save the times you have chosen in controlDict.
