RuntimeControl with surfaceFieldValue (v2012)

Dear All!

How can I combine the runtimeControl function object with the surfaceFieldValue function object?
In the following dummy example I get the following warning:

Code:

runTimeControl runTimeControl1 output:

    average: condition0 averages:

--> FOAM Warning :

    From virtual bool Foam::functionObjects::runTimeControls::averageCondition::apply()

    in file runTimeControl/runTimeCondition/averageCondition/averageCondition.C at line 151

    From function object: inletPres

Unprocessed fields:

        p

Code:

functions

 {

    inletPres

    {

        type            surfaceFieldValue;

        libs            ("libfieldFunctionObjects.so");

        writeControl    timeStep;

        log             yes;

        writeFields     no;

        regionType      patch;

        name            inlet;

        operation       areaAverage;



        fields

        (

            p

        );

    }



    runTimeControl1

    {

        type            runTimeControl;

        libs            ("libutilityFunctionObjects.so");

        conditions

        {

            condition0

            {

                type            average;

                functionObject  inletPres;

                fields          (p);

                tolerance       5;

                windowType      approximate;

                window          5;

                // groupID         1;

            }

        }

    }

 }

I have tried many combinations for the field name in the condition0 entry without any success.
It seems like the surfaceFieldValue is using some weird name for the results field which I wasn't able to figure out or they are just not compatible (it would be surprising)?

Thanks!

Hi,

It happens to be I am also trying to do something similar. I hope to test if it works soon, but I have to wait a bit until I can run the case, but in the past (v1712) we found out that the field name would need to be something as in <timeDirectory>/uniform/funtionObjectProperties. It is a bit of a weird construction, but based on how we did it in the past and also how I have now prepared my case, I would estimate that you would need to use

fields (areaAverage(inlet,p));

as in:

Code:

    runTimeControl1

    {

        type            runTimeControl;

        libs            ("libutilityFunctionObjects.so");

        conditions

        {

            condition0

            {

                type            average;

                functionObject  inletPres;

                fields          (areaAverage(inlet,p));

                tolerance       5;

                windowType      approximate;

                window          5;

                // groupID         1;

            }

        }

    }

I hope to be able to update you soon if it works, or if you can confirm, that would be great.

Cheers,
Tom

Hi!

Thank you very much! This is it. Working properly!

Thanks again! :)

EDIT:

In the postProcess folder it writes as "areaAverage(p)" which I have already tried so this seems to be a really inconsistent naming for me.

Has anyone accomplished this using probes? I.e. for convergence based on a local field value? I haven't had success with this yet. It seems that since probes doesn't use the "setResult" command, maybe these results aren't available to the runTimeControl utility?
