Combustion in complex geometry??

AdN

Hi! I'm modeling a combustion in a complex geometry. For that, I use CHEMKIN to modelise the chemical reaction and the combustion. I import all of this in FLuent, and now I want to specify where the reaction occur in my geometry. How can I do that???? Thank you for the answer. you can also e_mail me at: adnacademia@yahoo.fr P.S.Here a litte summary of my problem

I have a pressure inlet, that arrive on my condensed particule, and the combustion begin (with a certain pressure).

_____________ __________| -> gaz | condensed ->__________| particule

|_____________

| the combustion begin here
