Good morning (or whatever time it is with you).
I am using OF 2206 with interFoam and





I have a functionObject that looks and runs OK like this:

fieldAverage1
       {
        type                   fieldAverage;
        libs                    (fieldFunctionObjects);
        writeControl       writeTime;
        executeControl  writeTime;
              fields
              (
              U
                   {
                   mean               on;
                   prime2Mean     on;
                   base                time;
                    }
              );
       }

But actually during simulation I realized that I only want to calculate the average of the last 30 seconds. I looked into the User Guide (https://www.openfoam.com/documentati...ldAverage.html) and built the following FO:

       fieldAverage1
     {
         type                fieldAverage;
        libs            (fieldFunctionObjects);
         writeControl    writeTime;
         executeControl  writeTime;
         fields
         (
             U
             {
                 mean            on;
                 prime2Mean      on;
                 base            time;
                 window          2;
                 windowName      Uavg
                 windowType      exact;
             }
           );
         }

Now I always get an error message when I restart the simulation:

2]
[2] --> FOAM FATAL IO ERROR: (openfoam-2206 patch=221104)
[2] Entry 'windowType' not found in dictionary "stream.functions.fieldAverage1.fields"
[2]
[2]
[2] file: stream.functions.fieldAverage1.fields at line 0.
[2]
[2] From bool Foam::dictionary::readEntry(const Foam::word&, T&, Foam::keyType:ption, bool) const [with T = Foam::word]

Does anyone have an idea what I am doing wrong here?

You need a semicolon after

windowName      Uavg

probably, such that

windowName      Uavg;

Do you also know such situations where you wish you hadn't written something because it's a bit ashaming?

Anyway, so I was a bit glad that there seemed to be other problems with my simulation:

I still got the following error

[13] 
[13] --> FOAM FATAL IO ERROR: (openfoam-2206 patch=221104)
[13] Entry 'windowTimes' not found in dictionary "stream.fieldAverage1.U"
[13] 
[13] 
[13] file: stream.fieldAverage1.U at line 0.
[13] 
[13] From bool Foam::dictionary::readEntry(const Foam::word&, T&, Foam::keyType::option, bool) const [with T = Foam::FIFOStack<double>]
[13] in file ./src/OpenFOAM/lnInclude/dictionaryTemplates.C at line

But the error together with

Information regarding the number of averaging steps, and total averaging time are written on a per-field basis to the "<functionObject name>Properties" dictionary, located in <time>/uniform.

from https://www.openfoam.com/documentati...e.html#details

brought me to the conclusion that the uniform directory is the problem....

Many thanks for the input, it has brought me further!
