Passing material properties to other material properties

Hi All,
I was wondering if anyone knew the best way to pass a material property to another material property during a simulation.
In this case, I am using the refractive index as a 'flag' for a spatially dependent function, basically if n = 1, the point in the mesh has been activated and I'd like it to be left alone. If n = 0, it's fair game.
I have a 2d component (comp1) and a material (mat1).
No matter if I just use n, or root.comp1.mat1.n I get the yellow highlighting and the 'Unknown variable' message when I hover over the property.
I've attached a snip that shows the same issue with my refraction index function.
Also, if you know of a less hacky way to implement this I'd really appreciate hearing it.

Hi
I would try not in the material node but in the physics node, and redirect the k vector to "User Defined" and do your equation modeling there.
I believe, but I'm not sure as I'm not from COMSOL ;) that there are some differences in the way COMSOL treats data in the physics node, versus referred data from a material.
But only someone from Support can really tell us *the way*

Good luck

Thanks for the information. I'll give that a try and report back.
