Thus far, I can convert the interior boundary condition into a wall boundary condition, but when I try to convert the interior boundary condition into an interface, it is not available as a boundary condition in the GUI. I have looked at separating faces via marked cell registers but I receive the message below. I am using Pointwise to tag my boundary conditions, and it does not have access to labelling an interior boundary condition. The second image below shows my intended setup for boundary conditions. Do you have recommendations on how to best move forward?
