Mass Flow Outlet defined according to Murray's Law
 

Hi all,

I'm quite new to coding and fluent UDF programming and am looking for some help. I'm modelling blood flow in a coronary bifurcation and successfully implemented some udf functions. however, i want to specify the 2 outlets to be 0.55 and 0.45 of the inlet mass flow rate (flow partition according to Murray's law).

how can someone call the velocity inlet in a define profile macro at each time step so it can then be used to calculate a mass flow rate (for a transient simulation)?
