Hello Ramiro,

from my experience the turbulent Prandtl number must be between 0,3 and 0,7. By coarse resolutions even smaller than 0,3. If you use this thermal coupling postprocessor the standard BGK collision must be also enough. Dous your dynamics use the relaxation frequency from lattice cells or the global from parameters?
