I am pretty sure you need a complete watertight solid for that feature to work, so that you can assign inlet and /or outlet faces as seeds…

Hey John,
I created an open inner region for you, you can find it in the following link: https://www.simscale.com/workbench/?pid=8646589404810777427&mi=operation%3A4%2Cgeometry%3A1&mt=GEOMETRY_OPERATION
You should make a small change to your geometry. It’s missing one face, which I assume to be the floor:

As a result, the open inner region operation is not optimal, since this “door” and the floor are being considered the same face, which will cause you some trouble to set proper boundary conditions:
