Hi all

I need to be saved from throwing the workstation out the window... Joking but really frustrated with trying to get my BCs right. I am getting a converged solution but only when artificial walls are placed at my outlets.

I have a pic of my monitor points and they converge to the same value. I start with no pressure drop with the intent of lowering it and ideally getting the walls to drop down as well. I begin entering in negative pressures but the walls stay at 100% for face and area. I use a global initialization of zero to start since I am just trying to get a base point that makes sense.

My reference pressure is zero and my relative pressure set at -1. I should have vacuums pulling the fluid out of my outlets not stuff rushing in. To make convergence easier I have a slow mass flow rate of 0.1 kg going through a rather large volume.

I have consulted the modeling guide but that was not helpful. I have the most robust settings, but its giving me a non physical answer.

any ideas on where I could look?
