Hello,

I could affirm that I am a serious fluent user (10 years), and I have found this problem 4 years ago. I did almost everything imaginable to implement equilibrium air, but was impossible to cope with the molecular weight problem.

I have also contacted fluent experts in combustion by that time, and they could not give me a feasible awnser (for the density solver). For the pressure based solver you can always try to deactivate species transport and manage to put the species you want. But this not very usefull for high mach number.

So ye, I am anxious to see If somebody did it. I took it personal...

cheers
