Michael@UW is on a distinguished road
OpenFOAM v2106:
I have the following controlDict and run in parallel.
Code:
startFrom       latestTime;
startTime       0;
stopAt          endTime;
endTime         50;
deltaT          0.001;
writeControl    runTime;
writeInterval   1;
After it finishes at t=50s, I modify the endTime to 60, but it does not continue. I found there is a system/controlDict in each processor folder, and it just read the controlDict in the processor folders so the change in the case/system/controlDict has no effect.

So I have to do the following:
1. change the endTime in case/system/controlDict
2. reconstructPar -latestTime

3. decomposePar -latestTime -force
4. mpirun -np 4 pimpleFoam -parallel

It works but is annoying. I expect I just need to modify the case/system/controlDict and continue running the case in parallel.

Does anyone have the same problem or I miss something?
