Hello,

I am running an simulation where I require heat generation in a fluid flow. Currently I am using buoyantSimpleFoam however, I believe this problem can be expanded to all solvers that have fvOptions implemented. I am implementing my heat generation terms by using the points terminology and the scalarSemiImplicitSource. My goal is to have a list of points and then there respective heat generation terms as well. (Below I have given an example with two points). The issue is that the points only use the first heat generation term, i.e. the (10 0). I have tried putting them into a list as well, i.e. h ((10 0) (1000 0)). However that just errors out OpenFOAM, with the error being that it expects a scalar instead of (. Is there any way around this with out having list a different source for each heat generation source?

Code:
 source1
{
    type            scalarSemiImplicitSource;
    active          yes;
    
    
    scalarSemiImplicitSourceCoeffs
    {
    selectionMode   points;
        points
        (
        (0.5 0.5 0)
        (2.5 0.5 0)
        );
        volumeMode            absolute;
        injectionRateSuSp
    {
       h      (10 0) 
          (1000 0);
         }
    }
}

As you have two heat generations, you need define two source not one
