Hi Ethan,

You can take a look of this CitcomCU package

This package has inflow/outflow boundary conditions on the bottom and
two opposite walls. By comparing the br-inflow package with ordinary
CitcomCU package, especially the file Boundary_conditions.c, I hope you
can learn something useful. Feel free and email me for further questions.

Also, the post by Brad Hager might be useful if you want a real "open",
instead of inflow, boundary conditions.
