Hi all,

I'm basing my simulation on the motorBike tutorial. My `controlDict` looks like this:

application     simpleFoam;

startFrom       startTime;

startTime       0;

stopAt          endTime;

endTime         100;

deltaT          1;

writeControl    timeStep;

writeInterval   10;

purgeWrite      0;

writeFormat     binary;

writePrecision  6;

writeCompression off;

timeFormat      general;

timePrecision   6;

runTimeModifiable false;

functions
{}

As far as I understand the `writeControl` settings, this should write out every tenth time step, i.e. 0, 10, 20, ..., 100. However, only the last time step is written to disk, just 100.

I've tried changing the `writeControl` setting to `runTime`, `adjustableRunTime`, modified the start and end times, but with no luck. I saw in another old post that included functions may be the issue, so I took them out (as you can see above), but that also didn't change anything.

I'm a beginner to OpenFOAM, so I feel like I'm making a simple mistake. Any advice on what to do?

I'm running v2012 on Ubuntu 20.04.

Hi Alok,

Where are you looking for your data? At the root of your case or in the processors directories?

The motorbike tutorial runs in parallel which means the data is distributed in the processor* directories. This is where the data is saved depending on your writeControl.

After the run, reconstructPar allows to reconstruct the data at the root of your case (one directory for each time step). In the motorbike tutorial, reconstructPar is used with the "-latestTime" option so it reconstructs only the last time step of the simulation.

Cheers,
Yann

Ah perfect!

Re-running `reconstructPar` without the `-latestTime` flag did the trick. Thank you!
