Solid Semi-Transparent BC adjacent Surface

    • aleo

      Hi everybody,
      I am simulating radiative heat flux (DO) within a semi-transparent medium, being adiabatic on all sides and a semi-transparent opening boundary condition.

      My question is: if I don't assign an adjacent material/fluid touching the solid semi-transparent body at the semi-transparent BC, what refractive index for the "outer zone" is chosen? This plays an important role, as the refraction/reflection/transmission for semi-transparent BCs is dependent on the fraction of n(outside)/n(inside).


      Thanks in advance and best,
