  Hello,
  
  What does index units mean? Does this have to match the default units set by the simulation?

  - INDEX UNITS: Only relevant when specifying a spatially varying equation in the INDEX properly described above. Specify the units (nm, um, m) of the x,y,z position variables.

  Yes, it is designed for space related index function. For dielectric material, the refractive index does not have any unit and is barely a numerical value.
