Hi, I'm using a modified conjugateHeatFoam solver to solve my multi-region problem. One of my equations has zeroGradient boundary conditions on each end (it's a 1D problem) and so I need to set a reference value for the equation. Usually I'd just use:

equationName.setReference(position, value);

But when it comes to the coupledFvScalarMatrix used in conjugateHeatFoam, what is the eqationName? For example, coupledFvScalarMatrix is set up like this:

coupledFvScalarMatrix equations(9);

    equations.set
    (
        0,
        new fvScalarMatrix
        (
            eqn0...
        )
    );
    
    equations.set
    (
        1,
        new fvScalarMatrix
        (
           eqn1...
        )
    );
    
    equations.set
    (
        2,
        new fvScalarMatrix
        (
            eqn2...
        )
    );

etc...

I've tried something like:

equations[0].setReference(position, value);

but this doesn't compile and gives the error "class Foam::lduMatrix has no member named setReference"

Can anybody help me out with this?
