Im trying to define a mass source directly into my fluid domain but I'm using non pre mixed combustion, so the only option is the pdf-mixture. I see options for mass source and mean mixture fraction source. I want the source to be 100% fuel (1 mean mixture fraction) but the units are in kg/m^3s, not a unitless quantity. Does that mean if I define my mass source as 10 kg/m^3s and mean mixture fraction source as 10 kg/m^3s thats the equivalent of saying 100% fuel?

Yes, that's correct.
