Hi, I’m trying to simulate blood flow in canine portal venous system and wonder is this right approach.
On pressure map and velocity map, there are too much pressures and abnormally high velocities (even higher than initial pressure-10mmHg and inflow boundary condition-150mm/s). I’m not sure which step is the problem.

Unfortunately, it's hard to obtain information about each outflow boundary condition in my lab due to lack of PC-MRI.
I can obtain flow velocity at the level of 1(inflow), 2(left main branch), and 3(right main branch).
Is there way to apply boundary condition at the middle of geometry?

제목: Re: need help for my project...
Thanks to your kind answer.
I made my mesh again with only two main outlets.
I have another questions, about time step and time step size.
I decided to make total 5 seconds of flow, so I write solver with time step size 0.01 / time step 500. But with this option, I got singula matrix error at approx. 200 time steps. Is there any options to fix this error?

again, singular matrix error occured from below settings
will it be helpful if I attached my project files?
