Hi FOAMERS;

In case if i have a single fluid(solving using simpleFoam) and have an inlet and outlet face, i can calculate the cumulative outflow at the boundary outlet face using swak4Foam functions specified in the "controlDict" file.

Now, if i extend the concept to "interFoam" where i deal with 2 fluids how can i know specific fluid outflow separately at the outlet face?
That is: cumulative outflow of fluid1 and cumulative outflow of fluid2.

Similarly, we have only 1 pressure value for every cell solved by the PIMPLE method. What can i do to explicitly have both the fluids pressure computed separately at specific point in the domain{using probeLocation can do this but how can i split pressures explicitly for both the fluids}?

Thanks and awaiting to know your suggestions;
Saideep

Hi;

Maybe just multiplying the outflux by alpha value can help me. But does any1 have an idea how can find the alpha values at the boundary face or in the boundary cell?

Alpha is no more a field that is being created in the createFields.H so how can i catch it using swak4Foam or any other?

Thanks;
