Hi Foamers,

I know that with fvOptions I can create an explicit source term for my equations in a pre-defined part of the mesh.

However, I am editing the icoFoam solver for taking into account a source term implicitly (fvm::Sp()) and so far everything works ok.

Now I am wondering how to tell the solver to take into account this source term just in some zone of the mesh (exactly as it does with fvOption with cellZone).

I think this should be done with "meshTools"...could anyone please give me some hints?

Thanks in advance,
Damiano
