Continue to run parallel

zxj160 · May 10, 2012, 13:12

Dear foamers,

I run a case in parallel from 0s to 2000s. The job has finished. But I want to continue to run the case in parallel from 2000s to 4000s. How can I achieve that?

Just change your controlDict file accordingly setting 2000 as startTime and 4000 as endTime.

blockMesh
setFields
funkySetFields -time 0
decomposePar
mpirun --hostfile $PBS_NODEFILE -np $np myFoamd -parallel

Is it mean that I only need to run the last command "mpirun --hostfile $PBS_NODEFILE -np $np myFoamd -parallel" after I change the controlDict?

Or can I use mapFields utility?

I have run the reconstructPar command for the first 2000s. How can I reconstructPar from 2000s to 4000s?

You just need the solver command and at the end you should run reconstructPar again.

Or startFrom latestTime. Then if you copy the case to another location, (using pyFoam of course), you do not have to take care of this controlDict entry.

As easy as: reconstructPar -time 2000:4000

Many thanks for your ideas. It can work now.
