Hello to all,


I would like to create a custom functionObject to use in laplacianFoam.



For this purpose, I need the parameter DT in the dictionary transportProperties.


I have:

functions
{
    myCodedFunction
    {
        type coded;
        libs (utilityFunctionObjects);
        writeControl runTime;
        writeInterval $writeInterval;


        // Name of on-the-fly generated functionObject
        name test;
        
        codeWrite
        #{
            // Lookup for T
            const volScalarField& T = mesh().lookupObject<volScalarField>("T");

            // Gets the DT coefficient from 
          const dictionary& transportProperties = mesh().lookupObject<IOdictionary>
          (
             "transportProperties"
          );    

            const scalar alpha (transportProperties.getScalar("DT"));

            Info << "Alpha is: " << alpha << endl;

        #};
    }

}

However, I get the error:

    request for dictionary transportProperties from objectRegistry region0 failed
    available objects of type dictionary are
4(fvSchemes fvOptions fvSolution data)

It the transportProperties not created yet? Am I looking for it in a wrong manner?
