Dear all,
i've managed to add a scalarTransport solver to my pisoFOAM simulation using the #includeFunc scalarTransport command.
This works fine as long as i have an inlet and can define an inlet condition for my scalar value s.

Now, for further simulations using cyclic boundaries, i want to implement a scalar source within my domain using the fvOptions dict and the scalarSemiImplicitSource entry. Following the approach taken in multiple thread here in the forum i added the following part to my fvOptions dict.

Tracer
{
    type            scalarSemiImplicitSource;
    active          true; //using yes doesn't change anything

    scalarSemiImplicitSourceCoeffs
    {
        selectionMode   points;
        volumeMode        absolute;
        points            
        (
            (32 29.1 0.5)
            (32 29.1 1)
            (32 29.1 1.5)
        );
        
        injectionRateSuSp
        {
            s   (1.0 0);
        }
    }
}

And the next line to my controlDict

libs  
(
      "libutilityFunctionObjects.so" 
);

The entry is debugged to the point where the solver starts running, but it does not use the above defined scalar source. The following error is printed:

--> FOAM Warning :
From function virtual void Foam::fv:: option::checkApplied() const
in file cfdTools/general/fvOptions/fvOption.C at line 118
Source Tracer defined for field s but never used
--> FOAM Warning :
From function virtual void Foam::fv:: option::checkApplied() const
in file cfdTools/general/fvOptions/fvOption.C at line 118
Source Tracer defined for field s but never used

So, the question is: Where did i make a mistake? Something seems to be wrong here.
