Hello foamers,

EDIT: replace "keyword" with "entry" in the title


I want to read a scalar from let's say constant/transportProperties.nu and store it into a keyword nu in 0/U.

One can achieve that by defining a third dictionary file that contains the keyword nu and its value, and this file is then #included in both transportProperties and 0/U, which is perfectly doable and valid.

However, I have problem doing that using codeStream:

/* file: 0/U */

NU #codeStream
{

    codeInclude
    #{
        #include "fvCFD.H"
    #};

    codeOptions
    #{
        -I$(LIB_SRC)/finiteVolume/lnInclude \
        -I$(LIB_SRC)/meshTools/lnInclude
    #};

    codeLibs
    #{
        -lmeshTools \
        -lfiniteVolume
    #};

    code
    #{
        const IOdictionary& d = static_cast<const IOdictionary&>(dict.parent().parent());

        dimensionedScalar nu
        (
           "nu",
           dimViscosity,
           d.db().lookupObject<IOdictionary>("transportProperties")
        );

        nu.writeEntry("", os);
        // or
        // os  << nu.value();
    #};
};


// ...

Re 44000;
L 0.06; // cm
U_inlet_x    #calc"$Re * $NU / $L";

But this gives me the following segfault:

Am I missing something here? Not sure where lies the problem. I am trying to debug it, but it's not a trivial task, and need to spend more time on that.

This seems to be a useful feature to use (i.e. getting access to another dictionary from other files and storing it in the dictionary entry of the same type), but I couldn't find much information online about it.
