Boundary conditions for the bifurcated arteries.
What I am doing is to repeat an experiment from a journal. It is a bifurcation with one inlet and two outlets.
My boundary condition is following:
outlet2: fixedValue ( Value uniform 0 ) ( I think this is "zero reference pressure" )
inlet: parabolic steady velocity
outlet1: zeroGradient ( fully developed )
outlet2: zeroGradient ( fully developed )
I use these boundary conditions from a journal. But the results is wired.
The blood only pass through outlet2 which "zero reference pressure present". It never pass through the other vessel.
Can someone point out errors for me?
Thanks a lot!
I am also doing the same problem. Single tube bifurcating in two.
The problem in your boundary condition is with pressure. I used following condition for pressure at following outlet and got the fluid(in my case air) from both the outlets:
value uniform 0;
How did you set up your case? Can u share the case file? How did u manage to apply parabolic profile at the inlet?
