pathak Guest Posts: n/a	Dear users, I have a doubt. While specifying the 'Pressure boudary' for scalar, is it mandatary to specify the mass fraction in case of multicomponet problems as in most of the cases the outlet concentration is unknown? kindly let us know if there is any way of avoiding the concentration input with pressure boundary condition. thank you, pathak
