Dear All,

Any one with experience on how to define a mass source term for fuel in a methane air reaction? I have a UDF that is suppose to define additional mass of ch4 in some specified cells in my computational domain but i am wondering of whether to put it under mass in the fluid panel or under ch4 in the fluid panel. Also, when you define an additional mass, it is suppose to affect the momentum, energy, etc and so is fluent going to know that an additional momentum source has been added and energy source has been added or one has to also defined these explicitly?

Thanks for your help in advance.
