Pressure at the inlet

[Aditya Bantwal]

Hi,

I have the static pressure waveform of blood pressure at the inflow. If I specify a Neumann BC at the inlet, can I use this static pressure as a boundary condition? Or do I need to provide the total pressure (static + dynamic)

Thanks,
Aditya


PS. This is for svFSI

I haven't used this in svFSI but I think you can apply the static pressure waveform as a Neumann BC at the inlet. Give it a try. In case it doesn't work, prescribing the pressure waveform via coupled BC can be considered. Here is a test case for a more complex closed-loop LPM. https://github.com/SimVascular/svFSI-Te ... losed-loop

svFSI takes only static pressure as the Neumann boundary condition and not dynamic pressure. You can output total pressure as one of the output quantities if you are interested.
