Time monitoring gamma in subvolume
 

Hi everybody!

I'm trying to simulate the movement of a propellant liquid inside a tank using the VOF solver and i would like to monitor the total volume of propellant helded within a subdomain (for example a cylinder inside a bigger cylinder) because i want to know how much propellant there is in a certain zone.

Could anybody give me some help please?

Thank you very much.
Bye
