Re: Applying a pressure boundary condition

hi,

We have been trying this model in our lab. Unfortunately, we are also facing the same problem.
I have done exactly the same thing which you have mentioned. We gave a pulsating pressure input to the inlet of the laminar flow. We were expecting a pressure wave propagation along the arterial walls. We could see a displacement in the arterial wall due to the pulsating pressure. Unfortunately, we were unable to see the wave propagation ( or in other words the speed of wave propagation was infinity). In a nutshell, we are not able to model arterial compliance properly. The wall is acting like a perfect rigid body.

I hope you might have seen this model.

Did you make any progress in this topic ?
