how to realize the premixed gas in the tube
 

I want to use PHOENICS to calculate the CH4/Air premixed gas flame propagating in the tube. But there is not such an example in the tutorials even in the library case. Would someone pleaese tell me how to realize such a project. Which model should be used and how to define the premixed gas in the tube. Thanks a lot!

What version of PHOENICS are you running? I'm pretty sure there *is* a library case just like that? What kinds of model do you want to use for combustion?
