Hi,

I am trying to calculate mole fraction of oxygen using OpenFOAM-2.2.x. I know how to get the mass fraction and molecular weight of oxygen but i don't know how to get the molecular weight of the whole mixture. I intend to use the mole fraction of oxygen as a boundary condition for the fuel inlet patch. Any ideas would be appreciated.

Thanks,
charles
