Sources in Multiphase Flow

I am trying to model a mixing tank with the following materials and components:
Material 1: Air (gas, dispersed fluid)
Material 2: AirWaterMixture (liquid, continuous fluid) with two components
Component 1: Air (transport equation)
Component 2: Water (constraint)
I am trying to model the transfer of gas Air (Material 1) to dissolved Air (Material 2.Component 1) with the following source term:
DOSource = K1*(dens)*(C1+0.001*C0-(AirWaterMixture.Air.mf))
where K1, dens, C1 and C0 are constants. I don't get any error when I define the problem, but when I start the solver, in the first iteration I get the following error message:
| ERROR #001100279 has occurred in subroutine ErrAction.
| NAME_MOD: Error finding variable "MASFRN_FL1_FL2"
I have been trying different things, but none of them work. Surprisingly, if I define the source term as:
DOSource = K1*(dens)*(C1+0.001*C0-(Air.vf))
I don't get any error, but this is not the correct definition of the source term.
Does anyone have any clue about what it causing this error? Or about any other way of modelling the transfer of Air in gas phase to dissolved Air in liquid phase?
Many thanks for your help,
