bubbleInterTrackFoam and Mass transport

I am trying to model mass transfer across a bubble interface using bubbleInterTrackFoam, but when I added the scalar transport equation into the solver, it does not solve anything.
The following is an excerpt of the solver. Any help and suggestions on how to make this work? Thank you
# include "continuityErrs.H" // Momentum corrector U -= fvc::grad(p)/AU; U.correctBoundaryConditions(); } //# include "solveBulkSurfactant.H" # include "species_transfer.H" interface.correctPoints(); # include "freeSurfaceContinuityErrs.H" } # include "updateMovingReferenceFrame.H" # include "volContinuity.H"
Info << "Solving the species field" << endl; DT = fluidIndicator*( DTA - DTB ) + DTB; solve ( fvm::ddt(C_O2) + fvm::div(phi - fvc::meshPhi(rho,U), C_O2) //+ fvm::div(phi, C_O2) == fvm::laplacian(DT, C_O2) );

I have the impression that you are now solving the convection-diffusion equation in two seperate domains (you can easily check that I think with a simple case).
For the mass transfer across the interface, you should somehow communicate between the patches freeSurface(Shadow).

I would like to know if you could share your bubbleInterTrackFam + Mass transport implementation with me. I'm working with the same topíc, a falling drop with the conjugated solute transport to the exterior, but I'm having trouble even setting the case. Any help is appreciated .

I am using bubbleInterTrackFoam to simulate a bubble rising in a liquid column.I got some error like bellow
Create dynamic mesh for time = 0
Selecting dynamicFvMesh dynamicMotionSolverFvMesh
Selecting motion solver: laplace
Selecting motion diffusivity: uniform
Reading field p
Reading field U
Reading/calculating face flux field phi
Found free surface patch. ID: 1
Found free surface shadow patch. ID: 0
--> FOAM FATAL ERROR:
Error in B-to-A face patchToPatchInterpolation.
From function freeSurface::makeInterpolators()
in file makeFreeSurfaceData.C at line 105.
Can anyone pls tell me what to do
