  3. What combination of options enables the “Non-Adiabatic Laminar Flame Speed” under the properties tab when solving a partially-premixed, non-adiabatic FGM diffusion flamelet model? I have tried activating and deactivating several different options and nothing seems to ungrey this option through the GUI?

      The partially premixed mixture properties are calculated by Fluent during the PDF table generation, so this option will only be active once the first PDF has been generated for a partially premixed combustion case. The Non-Adiabatic Laminar Flame Speed is compatible with the Steady Diffusion Flamelet or Chemical Equilibrium State relations, but unavailable for Unsteady Flamelets and Flamelet Generated Manifold (FGM).
