Dear chih

Depending on how accurate you want the model to be. I know that there is a way to program via ground to do this but for me I do things a little simpler. I just convert the fire growth / heat release rate into discrete time elements say 10 sec, then make each 'fire object' active for only to 10 sec time interval. I have found that using the discrete time method accurate enough for the fire modeling that I have been doing.

Hope this helps
