hey foamers,

I made a new solver based on scalarTransportFoam. I added a source term M0.

My problem:
The variable T (from scalarTransportFoam) exceeds the cell value of the source term M0. The source term value should be the maximum value.

My idea:
a query if T lager then M0 (in every cell). If its true set T=M0.

I find here this:
limit variable

I want to do it like this way in the simple.loop() of my .c

forAll(mesh.cellZones(), zoneI)
{
    const cellZone& cz = mesh.cellZones()[zoneI];
    const labelList& cells = cz;

 
forAll(mesh.cellZones(), zoneI)
{
    const cellZone& cz = mesh.cellZones()[zoneI];
    const labelList& cells = cz;

 
forAll(cells, iCells)
{
    const label cellId = cells[iCells];
            
    if (T()[cellId] > M0()[cellId])
    {
    T()[cellId] = M0()[cellId];
    }
}
}
}

but it didnt complie. I think the query is wrong.

Can anyone help me?
Best regards
