Mass flow rate at the outlet
 
I am trying to model blood flow in a bifurcation, I have pulsatile pressure at inlet and pulsaitile mass flow rates at the outlets. As there is no mass flow rate outlet in fluent, I have been trying to give negative values for a mass flow rate inlet bc at the outlets using UDFs. However the results seem to be all wrong ,I see only negative flow at the outlets.
Can you tell me what is the issue and what can be done.
Thanking you
Tejasvi

Hey Tejasvi. I am trying to model something similar and I was wondering if you found the solution?

Hi, can you be more specific..?? R you considering multiphase for this. ? if yes, you can directly define the mass flow rate.
you can let me know the kind of solver and method you haven chosen ? I can try helping you. !
