Upwind-like flux scheme on Central Foam

Dear all,

Is implementing an upwind-like flux scheme in rhoCentralFoam, will be easier. Can anyone has any experience with it.
I have looked at the following link: http://www.cfd-online.com/Forums/ope...-openfoam.html

But I need more reference. I am trying to implement AUSM scheme only. I am very new to OpenFoam. While running the wedge problem I am getting the following error.
