Hi, all: I have a question

I have a question about the pEqn.flux() in the PISO loop, for the incompressible(icoFoam) case, after solving the pressure correction equation:
phi -= pEqn.flux();
while in the compressible case (sonicFoam),
phi = pEqn.flux();
My understanding is the incompressible flow is just a special case for the compressible flow (rho=const), no matter the pressure correction equation looks like. Can anyone explain the difference for the two cases?
Thanks a lot!
