Simbelmynė is on a distinguished road

What is the most suitable method of constraining a scalar (tracer) to one of the phases, say the primary phase?

Is it to set the scalar diffusivity to zero in the secondary phase where no scalar transport should take place? I guess this treatment does not account for numerical diffusion though.

Limit fluxes of the scalar in the secondary phase to zero?
