Total Volume of a phase interFoam
 

Hello Foamers,

i wanted to ask. How can i write into a file of the total volume of a phase (lets say water) for the specific time steps in the whole domain. Should i use functions in controlDict?

I did something like that but how should i modify it?

functions
{
waterVolume
{
type volFieldValue;
libs (fieldFunctionObjects);

writeControl timeStep;
writeInterval 1;
writeFields false;
writeToFile true;
log true;
regionType all;

operation sum;

fields
(
V()*alpha.water
);
}
};

Thanks in advance:)
