Hey,

i have some problems with my combustion simulation. I use the partially premixed model and set the mean mixture fraction of the inlet to the value which produces the highest temperatures. i got this value from the pdf table. the problem is, that the combustion is not complete. the temperature is about 500k too low and there is still oxygen left. i use methane as fuel and air as oxidizer. the mean mixture fraction is at 0.05661896.

i hope that you have a clue of what is going wrong
