Species and reaction limits in FLUENT
 

I am trying to run combustion simulations in FLUENT (version 6.2.16), but it appears as though there is a limit of 100 species and 500 reactions for CHEMKIN imports. The chemistry models that I would like to use have far greater species and reactions than this (they are for n-heptane and iso-octane). Is there any way to increase these limits in FLUENT? Thank you for any help.
