Hello everyone,


I'm using the sprayFoam solver, and i need to understand how it calculates in detail the parcelsToInject at every time step.
The parcelToInject variable is calculated within ConeNozzleInjection.C (or in the equivalent file for other injection models) through the following lines:


template<class CloudType>
Foam::label Foam::ConeNozzleInjection<CloudType> parcelsToInject
(
const scalar time0,
const scalar time1
)
{
if ((time0 >= 0.0) && (time0 < duration_))
{
return floor((time1 - time0)*parcelsPerSecond_);
}
else
{
return 0;
}
}


my problem now it's that i'm not able at all to find how the codes calculates time0 and time1.
I looked for these variables throughout the whole foam folders, but they aren't calculated anywhere in a simple form such as:

time0 = ____


i don't really know how to find out how are calculated these variables.
Is anyone able to help me?


Thanks a lot,
Pippo
