I am doing flare simulation using Fluent. But the species number of our combustion mechanism (in Chemkin format) is larger than 50 (about 60). Is there still a limitation of 50 species for the latest version of Fluent?  

Thanks a lot and looking forward for your replay.

In the full version the limit used to be about 300 as no one thought we'd try anything that complex: I suspect it's bigger now!  

There may be a limit in the Student version. Do you really need that many intermediate species?

Thanks a lot for your reply@rwoolhou. 

Is there 300 species limitation for PDF? There is another mixing model only takes 50?

I am doing combustion mechanism reduction works now. I need to know the maximum species that Fluent can handle.
