Partially premixed combustion model may predict wrong temperatures for a premixed combustion simulation if fuel composition is not set correctly

If you use the partially premixed combustion model for a premixed combustion calculation (due to the greater accuracy obtained from the partially premixed combustion model), the temperature prediction might not be correct if you are modeling the partially premixed system by setting the fuel composition as the premixed mixture and the parameter f=1 in the whole domain. Instead of the above, set the fuel composition as pure fuel, and then set the mixture fraction in the domain correctly (i.e. equal to the mass fraction of the fuel in the pre-mixture).
