I would recommend to search for the thesis by Hrvoje Jasak, it contains the explanation of these algorithms, closely following the notation of OpenFOAM (or vice versa)

Hi
Could u please explain why solver takes reciprocal of diagonal elements of velocity matrix... code is volScalarField rAU(1.0/UEqn.A());? & whats the out put of the following code HbyA = rAU*UEqn.H(); ? |

I am also new to openfoam. My understanding is:
HbyA is H divided by A which equals to UEqn.H()/UEqn.A()= UEqn.H()*1.0/UEqn.A() = rAU*UEqn.H() |
