| (7–38)

A separate Flamelet library is required for each fuel and each combination of fuel/oxidizer inlet temperatures and pressure level. The libraries shipped with CFX are listed in Table 7.1: Flamelet libraries included with CFX. The files reside in the subdirectory: `<CFXROOT>/etc/reactions-extra/flamelet/`

where `<CFXROOT>` is the location of your CFX installation.
