Interior wall - microfluidics problem

I have a system with three domains:
1) A nozzle made of quartz 2) The nozzle is filled with water 3) The nozzle is inside an air-chamber
I use laminar flow, and the level-set module where I only define the domains with the water and air. I want to track the water-air interface and see how the mensicus deforms.
However when I try to compute, it complains that there is an undefined variable in the domain that is the quartz nozzle. So I wonder:
- how can it complain about a variable in an undefined domain?
- I want the quartz domain to just be a solid wall separating the two fluids.
In laminar flow, I define it as interior walls. But I still get this error.
Any suggestions on how to move forwards?
