There isn't an RCR boundary condition implemented in the N-S solver. I attempted this a year or so ago, but got bogged down.

There is a Womersley velocity boundary condition implemented.

If you would like to work on contributing this feature. I would be willing to help.

Dear all,

I am trying to do a cardiovascular simulation by using Incompressible N-S solver in Nektar++. Here I have two questions about setting boundary conditions.

First, how can I set RCR(windkessel model) boundary condition if I use Incompressible N-S solver? Is there any similar input file I can find?

Second, do I need to make all the variable dimensionless when I set boundary conditions?

Thank you very much!

Best,

Zhen
