Hi Graeme,
The convective term can formally be written:

div(rUU) = div((rU)U) = div(fU) = fvm::div(phi,U)

So both, the mathematical expression and the c++ translation of it are correct in the aforementioned webpage.

Hi Dragos,

I confess that I don't know enough to follow that completely, but I'll take your word for it.

You don't need to know Fluid Mechanics for that, it is just a replacement: f = rU
Nothing more!
