Hello everyone,

I would like to use the averaging function of OpenFOAM for my velocity and pressure field. But not just from the beginning, but from 0.5 seconds to 1 second. Does anyone know how it works?

I have bnot found a solution so far. I have also found, that you can add "timeStart" und "timeEnd" to your controlDict but it does not work for me. The averaging still begings from 0 seconds.

functions
{
fieldAverage1
{
type fieldAverage;
libs ("libfieldFunctionObjects.so");
writeControl writeTime;
timeStart 0.5;
timeEnd 1;

Does anyone know whats wrong or generally how to solve my problem?

Hi Friend!

I use something similar and it is working for me!

    fieldAverage1
    {
        type            fieldAverage;
        functionObjectLibs ("libfieldFunctionObjects.so");
        enabled         true;
        outputControl   outputTime;
        timeStart       70;
        fields
(

...

)

P.S. I use OF 2.3.1

Hi syavash!

Thanks for your reply! I am using the OpenFOAM-dev version. Maybe thats the problem, why startTime and timeEnd are not working.

Does someone else know a solution?

So what version of OpenFOAM are you using? The timeStart and timeEnd options got added in 2.0.x
