I am trying to add a volumetric heatsource in laplacianFoam, when i run case this error appears. What are the issue?

You are using codes source and operators which are not defined are being used. -= operator is used for scalar and dimensionedScalar.

[divyesh]

source
{
    type    scalarCodedSource;
    active    true;
    name    source;    

    scalarCodedSourceCoeffs
    {
        selectionMode    all;
        fields    (T);


    codeInclude
    #{
    #};

    codeCorrect
    #{
        Pout<< "**codeCorrect**" << endl;
    #};


 codeAddSup
    #{
    const Time& time = mesh().time();
    const vectorField& C = mesh().C();
    const scalarField& V = mesh_.V();
    scalarField& source = eqn.source();
             forAll(C, i)
             {
                            source[i] -= (exp(time)*((sqr(C[i].x()))-2.0)*V[i]);
             };

    #};
 
codeConstrain
    #{
        Pout<< "**codeConstrain**"<< endl;
    #};
    }
}

This is my code for fvOptions.
Should I put = instead of -= ?

Hello divyesh, did you eventually end up finding a solution on how to implement a source term for your field T using fvOptions? I am currently trying to do the same thing (different term, but same metthod), but keep running into unsolved errors..
