Hi guys,

I've been using OpenFOAM for a while, and this is the first time that I've encountered this minor but annoying problem. I have set my "writeControl" to "runTime" with interval of 0.1, which should write the simulation results in 0.1s intervals (0, 0.1, 0.2 etc.), but instead I'm getting folders for 0, 0.0999999999, 0.19999999 etc. It's rather easy, but time consuming to fix by renaming all the folders, but I'm wondering if there is a way to make sure all folders are named for the specified time in controlDict.

Thanks,

John

p.s. I do not use adjustable time step option as it sometimes enforces very very small time steps (1e-9) and unnecessarily slow down the simulation process (compare to the same simulation using constant time step of 1e-6 without running into any problem).

Maybe post your controlDict settings. It would be of help.

Sorry for the delay in reply, the email notification probably ended up in spammail box and I forgot to check the forum until today. The maxCo was required by the solver for some reason, but shouldn't effect the writeControl, right?

Here's my controlDict:

application     pimpleDyMFoam;

startFrom       startTime;

startTime       0;

stopAt          endTime;

endTime         10;

deltaT          2e-06;

writeControl runTime;

writeInterval   0.1;

purgeWrite      0;

writeFormat     binary;

writePrecision  12;

writeCompression uncompressed;

timeFormat      general;

timePrecision   12;

runTimeModifiable yes;

adjustTimeStep  no;

maxCo           0.05;

maxDeltaT       1e-6;

Try:

writeControl adjustableRunTime;

Best,

Thanks for the input, tried that, same result, though =/
I've renamed all the folders manually already, anyway.
On a side note, I really should check my thread subscription notification setting, I did not see your post until today.
