[求助] Eric: how to simulate laminar Bunsen flame

daoyinliu

How to simulate laminar Bunsen flame? Writing codes and codes by myself of numerical methods, or via exsisted packages?
Writing codes by myself will take lots of time, but till now i can not find useable packages for simulating laminar bunsen flame?
Eric, would you suggest me some valuable free packages?  I have noted your good job of combustion simulation, and it seems it is easy for you to complete it.
If there is no valuable free packages,as you known, would you give me some advice about how to writing codes by myself?
Another thing is, do you think writing codes step by step by oneself is a foolish way to implement laminar Bunsen flame, since it is a very basic problem of combustion and already researched by many persons?   

Thanks a lot.
