HELP!!!! To find the flux through a number of patches
 
Dear All

I have a case of two inelts and two outlets and i wanted to calculate the total flux to have an idea if my solution reached a steady state as i am using itnerFoam i know in control dict you can add functions such as below but how to add or sum all the flow rates of the four boundary patches*

#includeFunc flowRatePatch(name=inlet1)
#includeFunc flowRatePatch(name=inlet2)
#includeFunc flowRatePatch(name=outlet1)
#includeFunc flowRatePatch(name=outlet2)
