Hello sante_junior,
1. Absorptivity of zero means the solid is opaque. It should still participate in radiative heat transfer.
2. Please check out the settings for the turbulence fields in the...

Hello, Lasse -
I don't typically use the steady state solver, rather, I tend to use the transient solver with LTS.
One idea is to try the same problem with simpleParcelReactingFoam, which is a...
