Hi everyone,

I want to change my fvSchemes "on the Fly" during a simulation in simpleFoam. But I have to do so many simulation, that i want to write a script, which is changing it for me. I thought i could use Allrun for it, but I just don't know how. Maybe somebody here could help me. The conditions to change the fvSchemes could be a specific iterationstep like 100 or a timestep like 60 seconds. Further I'm thinking about starting with turbulance off in RASProberties and switching it on after 10 or 20 iterationsteps. Should someone be so kind as to help me, I would really appreciate his/her help.

Kind regards, Fabian

Quick answer: Function object "timeActivatedFileUpdate" should be what you're looking for. Example from the source code documentation:
Code:
fileUpdate1
{
    type              timeActivatedFileUpdate;
    functionObjectLibs ("libutilityFunctionObjects.so");
    outputControl     timeStep;
    outputInterval    1;
    fileToUpdate      "$FOAM_CASE/system/fvSolution";
    timeVsFile
    (
        (-1 "$FOAM_CASE/system/fvSolution.0")
        (0.10 "$FOAM_CASE/system/fvSolution.10")
        (0.20 "$FOAM_CASE/system/fvSolution.20")
        (0.35 "$FOAM_CASE/system/fvSolution.35")
    );
}
