[Fadil12]

can anyone tell me about what Foam Fatal IO Error is ? and how do i fix this ?

driftFluxFoam has been superseded and replaced by the more general
incompressibleDriftFlux solver module executed by the foamRun application:

foamRun -solver incompressibleDriftFlux

Thanks you

Hello,
As mentioned in the error: "keyword Vc is undefined in dictionary", you haven't defined Vc in constant/phaseProperties file

Take a look at an example tutorial: tutorials/incompressibleDriftFlux/dahl/constant/phaseProperties
Vc is defined in here.

Thanks
