Calculate flux for a number of boundary patches

mwmalkawi · February 17, 2020, 08:21

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)

I think flowRatePatch does not support multiple patches at the moment.

Instead, you can sum the output by using 'add' fuction object, I think.

Thank you HPE will you please kiondly provide me the context who you would write it in cotorl Dict

Thanks
