Hi all,

Apart of the discussion taking place >>here<< I need some more explanation for what I see in a pEqn.H file (part of a compressibleInterFoam solver).

Could anyone of you rewrite following code line in a mathematical way?
           pEqnComp =
              (fvm::ddt(p) + fvm::div(phi, p) - fvm::Sp(fvc::div(phi), p));
Actually I can't understand only the last part.... What does fvm::Sp (or fvc::Sp) do? What does it stand for?
