Hello there,
I'm using OF10 (rhoPimpleFoam). Previously I was modifying createFields.H file to get mu, cp, kappa etc. by using following example entry.

volScalarField mu
(
    IOobject
    (
        "mu",
        runTime.timeName(),
        mesh,
        IOobject::NO_READ,
        IOobject::AUTO_WRITE
    ),
    thermo.mu()
);

But I want to do this via functionobject in controldict. I tried following but It's not creating anything.

writeviscosity
{
    type            coded;
    libs            ("libutilityFunctionObjects.so" "libOpenFOAM.so");
    region          main;
    executeControl  timeStep;
    executeInterval 1;
    writeControl    writeTime;
    log             true;
    code
    #{
        #include "fvCFD.H"
        #include "volFields.H"
        const volScalarField& mu = mesh().thermo.mu();
    volScalarField mu
(
    IOobject
    (
        "mu",
        runTime.timeName(),
        mesh,
        IOobject::NO_READ,
        IOobject::AUTO_WRITE
    ),
    mu
);
    #};
}

Can you help me to make this idea work? It would be very practical for everyone trying to do such thing I believe.

You are almost there. In your first example, you are creating the field, registering it and using AUTO_WRITE to make sure that it is being written.


With your updated code, the created field goes out ouf scope immediately so there is nothing hanging about for a later AUTO_WRITE to do at all.


What you want is to write it yourself. Here's an example,
